How Vulvar Cancer Treatment Is Planned by Stage and Tumor Location

Key Takeaways

  • A stage IA vulvar tumor is defined as 2 cm or smaller with invasion of 1 mm or less, and at that depth the groin lymph nodes are usually not removed because involvement is so uncommon.
  • Tumors more than about 1 cm from the midline drain to one groin, so only that side is assessed; midline tumors on the clitoris or perineum require both groins to be checked.
  • Sentinel lymph node biopsy, offered for single tumors under 4 cm with no suspicious nodes, removes one or two nodes instead of the whole groin and markedly lowers the risk of lymphedema and wound breakdown.
  • Groin lymph node status is the strongest predictor of outcome in vulvar cancer, and a positive node typically adds radiation to the groin and pelvis, often with platinum-based chemotherapy as a sensitizer.
  • When a tumor involves the urethra, anus or bladder, chemoradiation is usually given first to shrink it so that a later operation can spare those organs.
  • Vulvar cancer recurs locally more often than many cancers, and women with lichen sclerosus remain at risk of new tumors, so follow-up examinations and self-checks continue for years.
Quick Answer

Vulvar cancer treatment is planned by stage, which describes how deep the tumor has grown and whether it has reached lymph nodes or other organs, and by where it sits on the vulva. Very early tumors are usually removed by local surgery alone; larger or midline tumors add lymph node assessment; node-positive or locally advanced disease typically combines surgery, radiation and chemotherapy, decided by a specialist gynecologic oncology team.

The biopsy result arrives on a Tuesday, and the first thing she does is search for the word the nurse used on the phone: stage. By evening she has a dozen tabs open and a single, sharper question than any of them answer. Not what vulvar cancer is, but what is actually going to happen to her, and why the plan for the woman in the online forum looked nothing like the one her doctor sketched on a notepad.

That gap is not a mistake. Vulvar cancer treatment by stage is deliberately individual, because two tumors of the same size can call for different operations depending on a few millimeters of depth or a centimeter of distance from the midline. Understanding those levers is the fastest way to make sense of a plan that can otherwise feel arbitrary.

This explainer walks through how specialists build that plan, what the numbers on a staging report mean, and what the weeks afterward usually look like, using only what mainstream medical evidence supports.

What does vulvar cancer treatment by stage actually mean?

Vulvar cancer is a cancer that begins in the outer female genitals: the labia, the clitoris, the opening of the vagina and the skin between them. About 9 in 10 cases are squamous cell carcinomas, meaning they arise from the flat skin-type cells lining the vulva, according to the National Cancer Institute. Rarer types include melanoma, adenocarcinoma of glands such as the Bartholin gland, and basal cell carcinoma, and each of those follows somewhat different rules.

Staging is the shared language oncologists use to describe how far a cancer has traveled. For vulvar cancer, the FIGO system (from the International Federation of Gynecology and Obstetrics) sorts tumors from stage I, confined to the vulva, through stage IV, where the cancer has reached the upper urethra, bladder, rectum, pelvic bone or distant sites. Lymph nodes in the groin sit at the center of that system, because they are the first place vulvar cancer tends to spread.

Treating by stage, then, means matching the scale of therapy to the scale of disease. A tumor that has barely dipped beneath the skin surface does not need the same operation as one that has reached the groin. Doing less for early disease avoids lifelong complications; doing more for advanced disease gives the treatment a fair chance of controlling it.

Two features of vulvar cancer make this matching unusually precise. First, the tissue is external and visible, so surgeons can measure tumors and margins directly. Second, decades of research have shown that depth of invasion, measured in millimeters on the pathology slide, predicts groin involvement with remarkable consistency. The stage is not a label handed down after the fact; it is the blueprint for every decision that follows.

Vulvar cancer stages explained in plain language

Most people meet the staging system as a letter-and-number code on a report. Here is what the codes describe, drawn from the National Cancer Institute’s patient treatment summary. Stromal invasion, the term you will see repeatedly, simply means how far the tumor has grown down into the connective tissue beneath the skin.

Stage What it describes Usual treatment approach
IA Tumor 2 cm or smaller, invasion 1 mm or less, confined to vulva or perineum Local excision of the tumor with a margin; groin nodes usually not removed
IB Tumor larger than 2 cm or invasion deeper than 1 mm, still confined to vulva Radical local excision plus sentinel node biopsy or groin node removal
II Any size, reaching lower third of urethra, vagina or anus; nodes negative Wider excision, node assessment; radiation added if margins are close
III Spread to groin (inguinofemoral) lymph nodes Surgery plus radiation to groin and pelvis, often with chemotherapy
IVA Reaches upper urethra or vagina, bladder or rectal lining, pelvic bone, or fixed or ulcerated groin nodes Chemoradiation, sometimes followed by surgery
IVB Distant spread, including pelvic lymph nodes Systemic therapy, radiation for symptom control, clinical trials

Notice how small the thresholds are. One millimeter of depth separates IA from IB, and with it the decision about whether to operate on the groin at all. Two centimeters of width does the same. Those cutoffs exist because studies cited by the NCI found that tumors within the IA limits almost never involve lymph nodes, while deeper tumors carry a real and rising risk.

A pathologist establishes depth on the biopsy or excision specimen, and clinical examination plus imaging fills in the rest. Only after surgery, when nodes have been examined under the microscope, is the stage considered final.

Why tumor location matters as much as stage

Two women can have identical stage IB tumors and leave the operating room with very different scars. The difference is geography. The vulva drains its lymph fluid to the groin on the same side, so a tumor sitting well to one side, generally more than a centimeter from the midline, is treated as a one-sided problem. The surgeon assesses only the groin nodes on that side. A tumor at or near the midline, on the clitoris, the perineum or the fourchette, can drain to either groin, and both sides are checked.

Location also determines what structures are at risk during removal. A cancer on the outer labium majus can be excised with a generous margin and closed with relatively little functional change. A tumor of the same size wrapped around the urethral opening or approaching the anal margin forces a harder conversation. Taking a full centimeter of healthy tissue in every direction might mean removing part of the urethra, with a risk of urinary leakage, or part of the anal sphincter, with a risk of bowel control problems.

In those settings, gynecologic oncologists often accept a slightly narrower margin, or deliver radiation to the area afterward, rather than sacrifice the organ. Sometimes the order is reversed: radiation with chemotherapy comes first to shrink the tumor away from the urethra or anus, so that a later operation can preserve function. This is one of the clearest examples of how location can reshape a plan that stage alone would not.

The clitoris deserves its own mention. Tumors here are midline by definition, so both groins are assessed. Surgery may or may not involve removing clitoral tissue depending on how close the tumor sits, and the effect on sexual sensation is a legitimate part of the pre-operative discussion, not an afterthought. Mayo Clinic notes that sexual side effects are common after vulvar surgery and that talking about them beforehand is part of good planning.

What actually happens during vulvar cancer surgery

Surgery remains the foundation of treatment for most stages of vulvar cancer, and the modern approach is far more conservative than it was a generation ago. The historic operation removed the entire vulva and both groins in one large incision. Today, surgeons remove the tumor with a rim of healthy tissue and address the lymph nodes through separate, smaller cuts, an approach the NCI describes as producing fewer complications without compromising control of the disease.

The tumor operation goes by several names. Wide local excision removes the cancer and a margin of normal skin. Radical local excision goes deeper, down to the layer of connective tissue over the pelvic floor muscles, and is the standard for anything beyond stage IA. Partial or radical vulvectomy removes a larger section of the vulva when the tumor is extensive or when several areas are involved. Surgeons aim for a margin of roughly 1 cm of healthy tissue around the tumor, a figure the NCI ties to lower rates of local recurrence.

For the groin, two options exist. Sentinel lymph node biopsy uses a tracer, typically a radioactive marker and a blue dye injected around the tumor, to identify the first one or two nodes that drain it. Only those nodes are removed and examined. If they are clear, no further groin surgery is needed. Inguinofemoral lymphadenectomy, the older approach, removes all the lymph nodes in the groin. It gives more complete information but carries substantially higher risks of wound breakdown and lymphedema, the chronic leg swelling caused by disrupted lymph drainage.

When a large area of skin is removed, a plastic surgeon may use a skin graft or a flap, tissue moved from the thigh or buttock with its own blood supply, to close the wound. The procedure takes place under general anesthesia, and most people stay in the hospital for several days depending on the extent of the operation, per the NHS.

Stage 1 vulvar cancer treatment: when the smallest tumors need the least

Stage IA is the one situation in vulvar cancer where the groin can safely be left alone. The tumor must measure 2 cm or less and invade no more than 1 mm into the underlying tissue. In that setting, the NCI reports that the chance of lymph node involvement is so low that removing nodes offers no benefit while exposing the patient to real harm.

The operation is therefore a local excision: the tumor plus a margin of normal skin, closed directly. Many women go home within a day or two. Wound care, checking for infection, and a follow-up visit to review the final pathology are the main tasks of the first fortnight. If that pathology unexpectedly shows deeper invasion than the biopsy suggested, the stage is revised upward and a second operation to assess the groin may be recommended. This is not a failure of planning; biopsies sample only part of a tumor, and final staging always waits for the full specimen.

Stage IB looks similar on the outside but changes the plan underneath. Once invasion exceeds 1 mm or the tumor exceeds 2 cm, node assessment becomes standard. For a single tumor smaller than 4 cm with no suspicious nodes on examination or imaging, sentinel node biopsy is the NCI-endorsed approach. Lateral tumors get a one-sided sentinel procedure; midline tumors get both sides. When the tracer fails to identify a sentinel node on a given side, that groin is fully dissected instead.

Stage II adds extension to the lower third of the urethra, vagina or anus without node spread. The excision is wider and often requires reconstructive closure. If the surgeon cannot achieve a clean margin without damaging the urethra or sphincter, radiation to the vulva afterward is a common addition.

One more scenario belongs here. Precancerous change, called vulvar intraepithelial neoplasia or VIN, has not yet invaded and is managed differently: by local excision, laser treatment or topical medicine chosen by the specialist, with close surveillance rather than groin surgery.

Stage III: what changes when lymph nodes are involved

The single most important fact on a vulvar cancer pathology report is whether cancer was found in the groin lymph nodes. The NCI states plainly that node status is the strongest predictor of outcome, more so than tumor size. A positive node moves the disease to stage III and shifts the plan from surgery alone to surgery plus radiation.

Here is the reasoning. Cancer cells that have reached one groin node may already have seeded others, including nodes deeper in the pelvis that surgery does not reach. External beam radiation, delivered from a machine outside the body in daily sessions over several weeks, can treat that whole region. The NCI summary notes that for women with positive groin nodes, adding radiation to the groin and pelvis after surgery improved outcomes compared with removing pelvic nodes surgically, a finding that established the current standard.

Chemotherapy is frequently given alongside radiation in this setting, not as a stand-alone treatment but as a radiosensitizer. A platinum-based drug, most often cisplatin, makes cancer cells more vulnerable to the radiation beam. The oncology team weighs the added benefit against added fatigue, nausea and blood-count effects, particularly in older or frailer women, and the decision belongs to them and the patient together.

Stage III has sub-levels based on the number of involved nodes, whether they are larger or smaller than 5 mm, and whether the cancer has broken through the node capsule into surrounding fat. Those details refine how much radiation is given and to how wide a field. They are also why a surgeon will sometimes recommend full groin dissection rather than sentinel biopsy when nodes look suspicious before surgery: knowing the full extent of node disease directly changes the radiation plan.

Radiation to the groin brings its own side effects, notably skin soreness in the folds and a higher long-term risk of leg swelling. Neither is trivial, and both are discussed before treatment begins.

What happens when vulvar cancer spreads: stage IV and locally advanced disease

Vulvar cancer spreads in three ways: by growing directly into neighboring structures, by traveling through lymph vessels to the groin and then the pelvis, and, less commonly, through the bloodstream to distant organs such as the lungs, liver or bone. Stage IVA covers the first two when they reach the upper urethra or vagina, the bladder or rectal lining, the pelvic bone, or when groin nodes are fixed to surrounding tissue or have ulcerated through the skin. Stage IVB means distant spread, and pelvic lymph node involvement is counted as distant for this purpose.

For locally advanced disease, the traditional answer was radical surgery that removed the vulva together with the bladder or rectum, a procedure called pelvic exenteration. It is still occasionally performed, but the NCI describes chemoradiation as the preferred first step for tumors that cannot be removed without sacrificing those organs. Radiation with a platinum sensitizer shrinks the tumor over several weeks, after which the team reassesses. Some women need no further surgery; others have a smaller, organ-preserving operation to remove what remains.

Distant spread changes the goal. Treatment aims to control the cancer, relieve symptoms and protect quality of life rather than to remove all disease. Systemic chemotherapy, meaning drugs that circulate throughout the body, is the mainstay. Immunotherapy with checkpoint inhibitors, drugs that release the brakes on the immune system’s response to cancer, has a role for some tumors depending on their molecular features, and the NCI summary lists it among options. Targeted radiation can shrink a painful groin mass or a bone deposit. Clinical trials are a legitimate option at this stage and are worth asking about directly.

Symptom control is treatment, not its absence. Pain management, wound care for ulcerated tumors and support for lymphedema all belong in the plan, and palliative care specialists are often involved early rather than late.

Who is usually offered surgery first, and who is asked to wait

Surgery comes first for the majority of women with stage I and II vulvar cancer, and for many with stage III when the nodes are not bulky. The reasons are practical: the tumor is accessible, pathology from the specimen gives the most accurate stage, and radiation can still be added afterward if needed.

Several groups are typically steered toward a different sequence. Women whose tumor involves the urethra, anus or bladder in a way that would demand organ removal are usually offered chemoradiation before, or instead of, surgery. Those with fixed, matted or ulcerated groin nodes fall into the same category, because attempting to cut out such nodes carries a high risk of leaving disease behind and of wound complications.

Fitness for anesthesia is the other major filter. Vulvar cancer is most often diagnosed in women over 60, according to Cleveland Clinic, and many patients live with heart disease, diabetes or lung conditions. A frail woman with an early tumor may still be an excellent candidate for a small local excision under regional anesthesia, while a full groin dissection might be judged too risky. In that case the team might choose sentinel biopsy alone, or radiation to the groin instead of surgery, accepting a different balance of risks.

Waiting has a specific meaning here. It rarely means doing nothing. It may mean treating a coexisting skin condition such as lichen sclerosus first so that the surgical field heals properly, optimizing blood sugar or nutrition for a few weeks, or completing the imaging and multidisciplinary review that every case should have before a knife is picked up. The NHS describes this team approach, with surgeons, radiation and medical oncologists, pathologists and specialist nurses reviewing each case together, as the standard route to a plan.

Pregnancy, though rare with this cancer, and a strong personal preference to preserve specific anatomy are also legitimate reasons to sequence treatment differently, and both deserve an unhurried conversation.

Is vulvar cancer easily treatable? What the evidence actually shows

The honest answer has two halves. Vulvar cancer that is caught while still confined to the vulva, with clear lymph nodes, is generally very treatable with surgery, and the NCI describes the outlook in that setting as favorable. Cancer that has reached the groin nodes is harder to control, and the more nodes involved, the more that is true. Distant spread is managed rather than eliminated.

The word easily is where caution is needed. Even early disease demands an operation on a sensitive part of the body, wounds that can be slow to heal, and years of surveillance, because vulvar cancer has a well-documented tendency to recur on the vulva itself, sometimes long after the first treatment. Recurrences near the original site are often treatable with further excision; recurrences in the groin are more serious. This is why follow-up visits continue for years and why any new lump, sore or change should be reported promptly.

Two biological pathways also shape the picture. Some vulvar cancers are driven by persistent human papillomavirus infection and tend to occur in younger women, often alongside a history of abnormal cervical screening. Others arise in older women from long-standing inflammatory skin conditions, especially lichen sclerosus, through a precursor called differentiated VIN. Mayo Clinic and the NCI both describe these routes. The second group carries a higher risk of new tumors developing in the surrounding skin, which affects how closely the vulva is watched afterward.

What treatable does not mean is that any single statistic applies to you. Published outcome figures pool women of different ages, stages and health, and your team can tell you where you sit within them. Ask them directly rather than relying on a number found online, and be wary of any source that quotes success rates without saying whose success and at which stage.

How long does it take to recover from vulvar surgery?

Recovery has a shape that most people are not warned about: the first days are dominated by the wound and the catheter, the first weeks by healing and mobility, and the first months by adjusting to a body that looks and feels different. Timelines vary with the extent of surgery, and the ranges below are typical patterns described by the NHS and Mayo Clinic rather than promises.

In hospital, expect a urinary catheter for the first day or several, particularly after surgery near the urethra, and drains in the groin if nodes were removed. Nurses will show you how to keep the area clean, often with a handheld shower or a jug of warm water after using the toilet, and how to dry it gently. Pain is managed with regular medicine prescribed by the team. Walking begins early, because it protects against blood clots in the legs, a recognized risk after pelvic and groin surgery, and you may go home with blood-thinning injections and compression stockings that the team will explain.

Once home, the vulvar wound typically takes several weeks to heal, and groin wounds can take longer, according to the NHS. Wound breakdown, where the edges separate before healing, is common enough after groin dissection that the NCI lists it among expected complications; it is treated with dressings and time rather than alarm. Sitting may be uncomfortable for a period, and a soft cushion helps. Most women are advised to avoid heavy lifting, swimming and sexual intercourse until the team confirms healing, usually at a follow-up visit around six weeks.

Radiation, when added, generally starts once wounds have healed and runs over several weeks of daily weekday sessions. Skin in the groin folds becomes red and sore toward the end, peaking a week or two after the final session, then settles.

Fatigue outlasts everything else. Energy commonly returns gradually over two to three months, sometimes longer after combined treatment, and gentle, regular activity speeds it more reliably than rest alone.

Side effects and long-term changes to plan for

Lymphedema is the complication women most often say they wish they had understood better. When groin nodes are removed or irradiated, lymph fluid from the leg can no longer drain freely and collects in the thigh, calf or foot. It may appear months or years after treatment and, once established, is managed rather than reversed. The NCI identifies full groin dissection as the main driver, which is precisely why sentinel node biopsy has become standard where it is appropriate. Early referral to a lymphedema therapist, skin care to prevent infection, and compression garments are the pillars of management.

Wound problems come next. The vulva and groin are warm, moist and constantly moving, which makes infection and separation of wound edges more likely than after surgery elsewhere. Careful hygiene, loose cotton underwear and reporting redness or discharge promptly all help.

Changes to urinary and bowel function depend on location. Removal of tissue near the urethral opening can alter the direction of the urine stream or, less commonly, cause leakage. Surgery close to the anus can affect control, and radiation to the pelvis can cause loose stools during treatment. Both problems have treatments, and pelvic floor physiotherapy is often part of the answer.

Sexual health and body image are legitimate medical concerns, not vanity. Scar tissue can narrow the vaginal opening, reduce lubrication or make penetration uncomfortable. Loss of clitoral tissue changes sensation. Mayo Clinic advises open discussion with the care team before and after surgery, and many centers offer psychosexual counseling, dilator programs and vaginal moisturizers as routine supports. Partners are welcome in those conversations.

Finally, the emotional weight of a cancer in an intimate area is real and often carried alone. Specialist nurses, counselors and peer support groups exist for exactly this reason, and asking to be connected with them is a reasonable request at any stage.

What people often get wrong about vulvar cancer treatment

Everyone gets the whole vulva removed. This was true decades ago and is the single most persistent myth. Current practice removes the tumor with a margin and treats the groin through separate incisions, as the NCI describes. Total vulvectomy is reserved for extensive or multifocal disease.

If the surgeon does not remove the lymph nodes, something was missed. For stage IA tumors, leaving the groin alone is the correct, evidence-based decision. Operating would add risk without benefit. Conversely, having nodes removed does not mean the cancer has spread; it means the depth of the tumor made checking necessary.

Chemotherapy alone treats vulvar cancer. For localized disease, chemotherapy works as a helper to radiation, not as a stand-alone therapy. It becomes the main treatment only when the cancer has spread to distant sites.

Vulvar cancer is a sexually transmitted disease. Some cases are linked to HPV, a virus so common that most sexually active adults encounter it, according to the CDC’s general HPV guidance. Many others arise from chronic skin inflammation with no viral link at all. Neither route is anyone’s fault, and shame has no place in the clinic.

Once treatment ends, follow-up is a formality. Vulvar cancer recurs on the vulva more often than most cancers recur locally, and women with lichen sclerosus remain at risk of new tumors. Examinations continue for years and self-checking between visits matters.

Older women should not be offered surgery. Age alone is not a contraindication. Many women in their 80s undergo local excision safely. Fitness, not birth year, guides the decision.

Sexual function is over. It changes, and for some the change is significant, but with support, time and treatment for scarring and dryness, many women resume a satisfying intimate life. Silence, not surgery, is the more common barrier.

Questions to ask your care team before treatment begins

A staging conversation moves fast, and the questions you wish you had asked tend to surface in the car park. Writing them down beforehand, and bringing someone to take notes, turns a monologue into a plan you actually understand. These are the ones that most directly shape what happens next.

  • What is my stage right now, and which parts of it are confirmed by pathology versus estimated from examination and scans?
  • How deep is the tumor in millimeters, and how does that number change what you recommend for my groin?
  • Is my tumor lateral or midline, and does that mean one groin or both will be assessed?
  • Are you planning sentinel node biopsy or full groin dissection, and why is that the right choice in my case?
  • Which structures are close to the tumor, and what is the plan if a clean margin would mean damaging the urethra, anus or clitoris?
  • Will I need radiation or chemotherapy, and is that decided now or after the surgical pathology comes back?
  • Has my case been reviewed by a multidisciplinary team, and can I have a copy of their recommendation?
  • What will the wound look like, how long will healing typically take, and who do I contact if it opens or looks infected?
  • What is my risk of lymphedema, and can I see a lymphedema specialist before treatment rather than after a problem starts?
  • How will this affect urination, bowel control and sex, and what support exists for each?
  • How often will I be seen afterward, for how many years, and what should I check for myself between visits?
  • Are there clinical trials I am eligible for?
  • If I want a second opinion on the plan, how do I arrange one without delaying treatment?

None of these questions is adversarial. Good teams expect them, and the answers you receive are the clearest measure of whether the plan has been built around you rather than around a protocol.

When to call your doctor

Some symptoms during and after vulvar cancer treatment need a same-day call to the team or an emergency department, not a wait for the next appointment. Keep the contact numbers you were given somewhere visible, and do not talk yourself out of using them.

Call urgently for a fever with shaking chills, especially if you are receiving chemotherapy, because a low white cell count can turn a minor infection into a serious one within hours. Call for a wound that becomes increasingly red, hot and swollen, that leaks pus or smells foul, or whose edges separate widely. Bleeding that soaks a pad within an hour, or that does not stop with firm pressure, is an emergency.

Leg symptoms matter after groin surgery. A calf or thigh that becomes painful, swollen, warm or red on one side may signal a blood clot, and sudden breathlessness or chest pain alongside it requires emergency care immediately. Do not wait to see whether it passes.

Call the same day if you cannot pass urine, if urine burns and you feel unwell, or if you develop severe abdominal or pelvic pain, persistent vomiting, or diarrhea that leaves you unable to keep fluids down during radiation. Sudden confusion, drowsiness or a rapidly spreading rash also warrant urgent contact.

Between scheduled visits in the years after treatment, report any new lump, ulcer, thickened or discolored patch on the vulva, persistent itching or soreness that does not settle, a new lump in the groin, or swelling of a leg that was previously normal. Local recurrence is often treatable, and the earlier it is found, the more options remain.

Nothing in this article replaces the judgment of the team that knows your case. When in doubt, call. Reassurance is a legitimate outcome of a phone call, and no nurse or doctor will think less of you for seeking it.

Frequently asked questions

What happens when vulvar cancer spreads?

Vulvar cancer spreads first to the groin lymph nodes, then to pelvic nodes and, less often, through the bloodstream to lungs, liver or bone. Groin involvement changes the stage to III and adds radiation, usually with chemotherapy, after surgery. Distant spread is stage IVB, where systemic chemotherapy, immunotherapy for eligible tumors and radiation for symptom control aim to manage the disease and protect quality of life.

Is vulvar cancer easily treatable?

Vulvar cancer confined to the vulva with clear lymph nodes is generally very treatable with surgery, according to the National Cancer Institute. Treatment becomes more complex once groin nodes are involved, and distant spread is managed rather than eliminated. Even early disease requires an operation in a sensitive area and years of follow-up because local recurrence is relatively common, so treatable is accurate but easy is not.

How long does it take to recover from vulvar surgery?

Hospital stays typically last from one to several days depending on the extent of surgery, and vulvar wounds usually take several weeks to heal, with groin wounds sometimes longer, according to the NHS. Most women are asked to avoid heavy lifting, swimming and intercourse until a follow-up around six weeks confirms healing. Fatigue commonly persists for two to three months, and longer after combined surgery and radiation.

What is stage 1 vulvar cancer treatment?

Stage IA vulvar cancer, meaning a tumor of 2 cm or less with invasion no deeper than 1 mm, is treated by local excision with a margin of healthy skin and no groin surgery. Stage IB, with deeper invasion or a larger tumor, adds sentinel lymph node biopsy or groin node removal on one or both sides depending on whether the tumor is lateral or midline.

Can vulvar cancer stages be explained simply?

Stage I is confined to the vulva, stage II reaches the lower urethra, vagina or anus without node spread, stage III involves groin lymph nodes, and stage IV means spread to the upper urethra, bladder, rectum, pelvic bone or distant sites. Millimeters of depth and centimeters of width separate the early stages, and node status is the pivot between surgery alone and combined treatment.

Why did my surgeon only remove lymph nodes on one side?

Lymph from the vulva drains to the groin on the same side, so a tumor located more than about 1 cm from the midline is assessed only on that side. Tumors at or near the midline can drain to either groin and require assessment of both. One-sided surgery reflects your tumor’s location, not an incomplete operation, and it halves the risk of lymphedema.

Does vulvar cancer treatment always mean removing the whole vulva?

No. Modern treatment removes the tumor with a margin of roughly 1 cm and addresses lymph nodes through separate small incisions, an approach the National Cancer Institute describes as reducing complications without compromising control. Total vulvectomy is reserved for very extensive or multifocal disease. Reconstructive techniques such as skin flaps can close larger wounds when they are needed.

What does vulvar cancer surgery recovery involve day to day?

Early days involve a urinary catheter, possible groin drains, regular pain relief and gentle cleansing of the area with water after using the toilet. Walking starts early to prevent blood clots. At home, loose cotton underwear, a soft cushion for sitting and daily wound checks are the routine. Wound edge separation is common after groin dissection and is treated with dressings rather than further surgery.

Is chemotherapy used for vulvar cancer?

Yes, but its role depends on stage. For localized disease with node involvement or tumors near the urethra or anus, a platinum-based drug is given alongside radiation to make cancer cells more sensitive to it. Chemotherapy becomes the main treatment only when cancer has spread to distant sites, sometimes alongside immunotherapy for tumors with suitable molecular features. The treating oncologist decides the regimen.

How long is follow-up after vulvar cancer treatment?

Follow-up continues for years because vulvar cancer has a recognized tendency to recur locally, and women with lichen sclerosus remain at risk of new tumors in surrounding skin. Visits are typically more frequent early on and space out over time, and include examination of the vulva and groins. Your team sets the exact schedule and will teach you what to look for between appointments.
