Getting Ready for Mohs Surgery: Medicines to Mention, Allergies, Implanted Devices and the Wait

The spot on the side of her nose had been there so long it felt like part of her face. A pearly bump, a little crust that never quite finished healing. The biopsy result came back as basal cell carcinoma, and the follow-up letter used a phrase she had to look up: Mohs micrographic surgery.

Now there is a plastic bag of pill bottles on the kitchen table, a blood thinner among them, a pacemaker card in her wallet, and a sheet of pre-visit instructions that raises more questions than it answers. Preparing for Mohs surgery turns out to be less about the skin and more about everything else attached to the person wearing it.

That is the right instinct. The surgery itself is a well-established, tissue-sparing technique. The parts that tend to trip people up are the medicine list, the allergy history, the device in the chest, and the long, quiet hours in the waiting room.

Mohs surgery: what to expect on the day

Mohs micrographic surgery is a way of removing skin cancer in thin layers, checking each layer under a microscope while you wait, and stopping only when the edges show no remaining cancer cells. The surgeon is also the person reading the slides, which is what makes the technique different from a standard excision sent off to a lab and reported days later.

The visit is almost always outpatient, and you stay awake. A local anesthetic, an injected medicine that numbs a small area of skin, is placed around the tumor. According to Mayo Clinic, that injection is usually the most uncomfortable part; once the area is numb, you should feel pressure and tugging rather than pain.

The first layer comes out shaped like a shallow disc. The surgeon marks it with colored inks, draws a map matching the marks to positions on your skin, and sends the tissue to an on-site laboratory. A temporary dressing goes on and you return to the waiting area. If the slides show cancer cells at one edge, the surgeon numbs you again and removes another thin layer from precisely that spot, guided by the map. Each of these rounds is called a stage.

When the margins are clear, the surgeon talks with you about repair. Small wounds may be left to heal on their own; many are closed with stitches; some need a flap of neighboring skin or a graft from elsewhere. Occasionally a separate reconstructive surgeon takes over. That conversation happens after the cancer is out, because nobody knows the final wound size until the last slide is read.

Skin cancers of this type are the most common cancers overall, and the great majority are basal cell or squamous cell carcinomas, according to MedlinePlus and the NHS. Mohs is one of several ways to treat them, chosen when precision and tissue-sparing matter most.

Who is usually offered Mohs, and who is asked to wait

Mohs is not used for every skin cancer. Mayo Clinic and the NHS describe it as most useful for basal cell and squamous cell carcinomas that sit where every millimeter of healthy skin counts: the nose, eyelids, lips, ears, fingers, toes and genitals. It is also favored for tumors that have come back after earlier treatment, for cancers with poorly defined borders or aggressive growth patterns, for large tumors, and for people whose immune systems are suppressed and who therefore face a higher chance of recurrence.

Standard surgical excision, curettage with electrodesiccation (scraping followed by heat), radiotherapy, and topical or light-based treatments for very superficial lesions remain reasonable options in other situations. Which route is chosen depends on the tumor type, its location, its size, your general health and your preferences. That decision belongs to you and the treating team together, and a good team will explain why one approach fits your case better than another.

Being asked to wait is different from being turned down. Teams commonly postpone when there is an active skin infection near the site, when blood pressure is poorly controlled on the day, when a person has had a very recent heart attack, stroke or coronary stent and the cardiologist wants antiplatelet therapy left completely undisturbed for a set period, or when an acute illness makes a long outpatient day unwise. Pregnancy does not rule out Mohs, since the anesthetic is local, but the team will want to know so they can plan positioning and any medicines used.

The point of the pre-visit questionnaire is exactly this triage. Answer it fully, even the parts that seem irrelevant to a spot on your nose. A missing detail discovered on the morning of surgery is the most common reason a Mohs visit is rescheduled.

Preparing for Mohs surgery: the medicines list your team needs

Write it down, or bring the bottles. Memory is unreliable when you are nervous, and a dermatologic surgeon planning a wound on your face genuinely needs the whole picture. Include prescription medicines, inhalers, patches, eye drops, injections, over-the-counter painkillers, vitamins and herbal products, along with the name of the clinician who prescribes each one.

What to mention	Why it matters for Mohs	What usually happens
Anticoagulants and antiplatelets (for example warfarin, apixaban, clopidogrel, aspirin)	Affect bleeding and bruising during and after surgery	Surgeon and prescriber decide together; most people continue them
Blood pressure medicines	Uncontrolled pressure increases bleeding	Usually taken as normal on the day
Diabetes medicines and insulin	Long waits and skipped meals affect blood sugar; high sugar slows healing	Team advises on timing; bring snacks
Steroid tablets, immunosuppressants, biologics	Slow wound healing, raise infection risk, may affect scheduling	Discussed in advance, rarely stopped
Isotretinoin or other retinoids	Can influence scarring and repair choices	Surgeon plans reconstruction accordingly
Supplements such as fish oil, vitamin E, ginkgo, garlic, ginger	Some have mild antiplatelet effects	Often paused before surgery on the team’s advice

Notice the pattern in the right-hand column. The default, per Mayo Clinic and Cleveland Clinic guidance, is to keep taking prescribed medicines unless the surgeon or prescriber specifically tells you otherwise. Your job is disclosure, not editing.

Also mention anything you take irregularly: a sleeping tablet, an occasional anti-inflammatory for a bad knee, a migraine medicine. Tell them about recent courses too, such as antibiotics finished last week or a steroid injection last month. If you use cannabis, nicotine products or drink alcohol most days, say so plainly; these affect anesthetic response, bleeding and healing, and no one on the team is there to judge.

Mohs surgery and blood thinners: why nobody should stop them on their own

This is the question that keeps people up at night, so here is the plain version. Anticoagulants and antiplatelet medicines are prescribed to prevent clots that cause strokes, heart attacks, pulmonary emboli and stent blockages. The consequence of a clot is life-altering. The consequence of extra bleeding from a skin surgery is, in nearly every case, manageable in the room.

For that reason, Mayo Clinic and Cleveland Clinic both advise against stopping blood thinners before Mohs unless the prescribing clinician has specifically agreed. Dermatologic surgeons are used to operating on people who take them. They apply firm pressure, use cautery (a heated or electrical tip that seals small vessels) and choose repairs with bleeding risk in mind. What they cannot easily manage is a stroke caused by a gap in warfarin or a stent that clots because clopidogrel was skipped.

The medicines work in different ways, which is why the conversation should involve the prescriber. Warfarin lowers the activity of several clotting factors and takes days to wear off and days to return to a protective level. The newer direct oral anticoagulants act quickly and clear within roughly a day or two, so even a brief pause matters. Aspirin and clopidogrel act on platelets, the sticky cell fragments that plug small wounds, and their effect lasts for the lifespan of those platelets. Each drug therefore has a different risk profile if interrupted, and only the clinician who knows why you take it can weigh that risk.

What you can do: tell the Mohs team exactly what you take and why, ask whether they want to contact your cardiologist or general practitioner, and take the medicine as usual on the morning of surgery unless you have been told otherwise in writing. Expect a bit more bruising, plan for a firmer pressure dressing, and understand that this trade-off is the safe one.

Supplements, herbal products and over-the-counter painkillers

People tend to leave supplements off the list because they do not think of them as medicine. Surgeons think of them differently. Fish oil, vitamin E, ginkgo, garlic capsules, ginger and turmeric extracts, and high-dose omega-3 products all have mild effects on platelet function or clotting in laboratory and clinical reports. None is as potent as a prescribed anticoagulant, but combined with one, or taken in large amounts, they can add to oozing during a long procedure and bruising afterward.

Non-steroidal anti-inflammatory drugs, the class that includes ibuprofen and naproxen, work by blocking enzymes involved in inflammation and pain, and in doing so they also dampen platelet activity. Many Mohs teams ask people to avoid them in the days before surgery when they are being taken casually for aches rather than on prescription. Acetaminophen, which relieves pain through a different pathway and does not affect platelets, is often the suggested alternative for the run-up. This is general guidance drawn from Cleveland Clinic and Mayo Clinic patient information; your own team will tell you what they prefer, and if an anti-inflammatory has been prescribed for a condition such as arthritis, the prescriber decides.

A few other things deserve a mention. Alcohol widens blood vessels and can increase bleeding; teams commonly ask you to avoid it for a short period before and after surgery. Nicotine narrows small blood vessels and starves healing skin of oxygen, which matters enormously for flaps and grafts; the NHS notes that smoking slows wound healing generally. Caffeine is fine in normal amounts, though a very jittery morning does not help anyone holding a scalpel near your eyelid.

Bring the supplement bottles with you or photograph the labels. Product names vary, and the surgeon cares about ingredients, not branding.

Allergies that matter: local anesthetic, antibiotics, tape and latex

An allergy is an immune reaction to a substance, and it is different from a side effect. Both matter, but the team will ask about them separately, so it helps to know which is which.

Start with local anesthetics. True allergy to the amide anesthetics used in nearly all Mohs procedures, such as lidocaine, is rare. Many people who report a lidocaine allergy actually experienced palpitations, light-headedness or trembling from epinephrine, a medicine added to the anesthetic to reduce bleeding and prolong numbness. That reaction is a pharmacologic effect, not an allergy, and knowing the difference lets the surgeon adjust rather than abandon the plan. Describe what happened, when, and where, and let the team interpret it.

Antibiotic allergies come next. Not everyone receives antibiotics around Mohs, but some do, particularly with grafts, wounds in certain sites or specific medical histories. Penicillin, sulfonamide and cephalosporin reactions are the ones most often relevant. Say whether the reaction was a rash, swelling of the lips or throat, breathing difficulty or a stomach upset; the severity changes the alternatives.

Then there are the things that touch the skin. Adhesive tape allergy and reactions to topical antibiotic ointments are common enough that many surgeons prefer plain petroleum jelly for wound care, as Mayo Clinic and Cleveland Clinic advise. Iodine or chlorhexidine skin-prep sensitivities, latex allergy, and reactions to surgical glue or specific suture materials should all be mentioned. If you have ever had contact dermatitis from a dressing or a bandage, describe the pattern.

Finally, food and environmental allergies are less directly relevant but still worth stating, especially any history of anaphylaxis, a severe whole-body allergic reaction. Bring your emergency adrenaline auto-injector if you carry one. The team would rather know about a risk that never materializes than discover one mid-procedure.

Mohs surgery with a pacemaker, defibrillator or other implanted device

A pacemaker is a small implanted device that sends electrical impulses to keep the heart beating at a steady rate. An implantable cardioverter-defibrillator, or ICD, monitors the heart rhythm and delivers a shock if it detects a dangerous one. Both are sensitive to outside electrical signals, and that is the whole reason your surgeon needs to know.

Electrosurgery, the use of an electrical current to seal small blood vessels, is routine during Mohs. In its most common form, current passes from a handpiece through your body to a grounding pad. That current can be misread by a pacemaker as heart activity, causing it to pause, or misread by an ICD as a dangerous rhythm, prompting an unnecessary shock. These events are uncommon and usually brief, but they are avoidable, and dermatologic surgeons have well-rehearsed workarounds.

Depending on your device and the surgical site, the team may use bipolar cautery (current passes only between two tips of a forceps, not through your body), heat cautery (a hot wire with no current entering you), short bursts placed well away from the device, or pressure and sutures alone. For some ICDs and some procedures near the chest, they may liaise with your cardiology team about temporarily adjusting settings with a magnet or programmer and monitoring your rhythm during surgery.

Bring your device identification card, which lists the manufacturer, model and the clinic that follows you. Mention the date of your last device check if you know it, and whether you depend on the pacemaker constantly or only occasionally.

Other implants count too. Deep brain stimulators, spinal cord stimulators, cochlear implants, insulin pumps and continuous glucose monitors can all be affected by electrosurgical current or by positioning on the table. Metal plates, screws and hip or knee replacements do not interfere with cautery, but they matter for the antibiotic conversation covered next. When in doubt, list every implanted item; the team will decide which are relevant.

Artificial joints, heart valves and other conditions the team asks about

People with prosthetic joints or artificial heart valves often arrive with a specific worry: do I need antibiotics before skin surgery to protect the implant? The honest answer is that Mohs is performed on skin that has been cleaned and is not infected, and current guideline thinking treats most clean skin surgery as low risk for seeding an implant. Some situations change that calculation, such as a recent joint replacement, a wound in a high-bacteria area, a graft, or a history of prosthetic infection. Your surgeon may want to consult the orthopedic or cardiac team. State the facts and let them make the call; do not take leftover antibiotics on your own.

A short list of other conditions genuinely shapes the plan:

• Diabetes affects wound healing and infection risk. A long, unpredictable day can also upset blood sugar, so bring your meter, insulin or tablets as instructed, and snacks.
• Immune suppression from transplant medicines, chemotherapy, certain biologics or HIV changes healing, infection risk and, in some cases, how aggressively the team monitors for new skin cancers afterward.
• Bleeding disorders, liver disease and kidney disease all influence bleeding and how medicines are cleared.
• Heart failure, angina or breathing problems affect how long you can lie flat, and the team may adjust positioning or breaks.
• A history of fainting during injections or blood tests is worth mentioning so staff can have you lie down for the anesthetic.
• Keloid or thick scarring after earlier cuts guides the choice of repair.
• Anxiety, claustrophobia, dementia or hearing loss are not obstacles, but they change how the team communicates and whether a companion should stay in the room.

None of these usually rules out surgery. Each one simply changes a decision somewhere along the day, and the earlier the team knows, the smoother that decision is.

How long does Mohs surgery take, and how to handle the wait

Nobody can tell you in advance. Mayo Clinic advises setting aside several hours, and some visits run to most of a day. The reason is structural: each stage requires the tissue to be frozen, sliced, stained, mounted and read, and Cleveland Clinic patient information puts that laboratory turnaround at roughly an hour per stage. One stage might clear you in a morning. Three stages plus a flap repair fills the afternoon.

Most of that time is waiting, with a bandage on your face and no clear end point. Treat it like a long-haul flight and pack accordingly.

• Something absorbing to read or watch, with headphones and a charger.
• Snacks and a drink, since the anesthetic is local and eating is usually allowed and encouraged. Confirm this with your team, particularly if you have diabetes.
• A sweater or wrap; waiting rooms and procedure rooms run cold.
• Reading glasses, hearing aids, and your medicine list.
• Any medicine you take at a set time, so you can take it on schedule.

Bring a companion if you can, or arrange for one to collect you. You may be told you cannot drive if the wound is near an eye, if a bulky dressing limits movement, or simply because you have been sitting anxiously for hours. Cleveland Clinic recommends having someone to drive you home.

Ask at check-in whether you may step outside between stages and how they will reach you. Some teams allow a short walk; others prefer you nearby because the next stage begins the moment slides are read. Do not schedule anything else that day, and warn work that you may be unreachable.

One more thing about the wait: multiple stages are not a sign that something went wrong. Skin cancers often extend further under the surface than they appear on top, like roots under a weed. Removing them layer by layer is the technique working as designed.

Preparing for Mohs surgery at home: the week before and the night before

Once the medicine and device conversations are done, the rest is domestic.

In the week before, get any questions about medicines answered and written down, ideally by the person who prescribes them. Arrange time off; many people are advised to avoid strenuous activity for a period after surgery, so a Friday procedure followed by a quiet weekend is a common choice. Stock the bathroom with plain petroleum jelly, non-stick gauze and paper tape if your team recommends them, and buy soft foods if the wound will be near your mouth. If you smoke, this is a good moment to stop or pause; even a short break improves oxygen delivery to healing skin, and the NHS lists smoking among the factors that slow wound healing.

The day before, sleep as well as you can and skip alcohol if your team has asked you to. Confirm your lift home and your childcare or pet arrangements.

On the morning:

• Eat a normal breakfast unless you have been told otherwise, and take your usual medicines with water.
• Shower and wash your hair; you may be asked to keep the dressing dry afterward, which makes hair washing awkward for a day or two.
• Skip make-up, moisturizer, hair products near the site, perfume, and jewelry anywhere near the surgical area.
• Wear a shirt that buttons or zips at the front so nothing has to be pulled over a bandaged head or ear.
• Arrive a little early with your medicine list, device card, insurance or referral paperwork and your waiting-room kit.

Expect to have the site photographed, the diagnosis confirmed against the biopsy report, the spot marked with a pen, and to be asked to confirm the location yourself. That double-check is routine and worth doing carefully; biopsy sites can fade over weeks, and you are the best witness to where the lesion was.

What the following days and weeks usually look like

The first evening is mostly about pressure and elevation. You will leave with a firm dressing that the team usually asks you to leave in place for a set time, often overnight or a day, before starting wound care. Keeping the area raised above the heart, which for the face means sleeping propped on extra pillows, limits swelling. Mayo Clinic notes that some bleeding, swelling and bruising are expected, especially around the eyes, where loose tissue soaks up fluid like a sponge.

Pain is generally mild and often managed with acetaminophen; your team will tell you what they prefer and whether anti-inflammatories are acceptable once the risk of early bleeding has passed. Daily care usually means gentle cleansing, a thin layer of petroleum jelly to keep the wound moist, and a fresh non-stick dressing. Moist healing forms less crust and tends to scar better than letting a wound dry out.

Stitches, if used, are commonly removed within about one to two weeks depending on the site, according to Cleveland Clinic; the face heals faster than the back or legs. Wounds left to heal on their own take longer and pass through a phase that looks worse than it feels, with a moist red base that slowly contracts.

Activity restrictions matter more than people expect. Bending, heavy lifting and vigorous exercise raise blood pressure in the head and can restart bleeding or strain a repair, so teams typically ask you to take it easy for a defined period. Swimming and soaking are usually off the table until the wound has sealed.

Scars mature slowly. A pink, firm line at one month is normal; most scars soften and fade over many months, and your team may suggest sun protection and gentle massage once healed. A follow-up visit checks the wound and reviews the final pathology. After any skin cancer, regular skin checks continue, because having had one raises the likelihood of another.

What people often get wrong about preparing for Mohs surgery

Some of these myths are harmless. A few can cause real trouble.

Stopping the blood thinner to be helpful. This is the one that worries surgeons most. A person pauses warfarin or an antiplatelet for a few days because it seems sensible, tells no one, and walks in with a raised stroke risk to prevent bruising that the team could have handled. The rule, per Mayo Clinic and Cleveland Clinic guidance, is that only the prescriber changes the prescription.

Fasting from midnight. That instruction belongs to general anesthesia. Mohs uses local anesthetic, and arriving hungry only makes the long wait harder and the risk of fainting higher. Eat, unless you have been specifically told not to.

Several stages mean the surgeon missed something. They mean the cancer had extended beneath the surface, which is precisely why this technique was chosen. Removing another thin layer from the exact spot is the method, not a mistake.

The hole will be the size of the spot. The visible lesion is often the tip of something wider. Surgeons are careful not to predict wound size, and reconstruction is discussed only after the margins are clear.

A lidocaine allergy from the dentist. As covered earlier, a racing heart after a dental injection is usually the epinephrine, not an allergy. Describe it; do not self-diagnose it.

Skipping the pacemaker mention because it is far from the face. The current from standard electrosurgery travels through the body regardless of where the incision is. The device always needs to be declared.

It is only skin, so it does not count as surgery. It is surgery, with a wound that needs care, activity limits, and a healing timeline measured in weeks. Planning for it as such is the single best predictor of a calm recovery.

Questions to ask your care team

Bring these on paper. Waiting rooms are poor places for recall, and a written list signals to the team that you want a real conversation.

• Which of my medicines, if any, do you want changed before surgery, and will you confirm that with the doctor who prescribes them?
• Should I take my usual morning medicines, including my blood thinner and blood pressure tablets, on the day?
• Are there supplements or over-the-counter painkillers you would like me to pause, and for how long?
• I have a pacemaker or defibrillator (or another implant). How will you manage cautery, and do you need to speak with my cardiology team beforehand?
• I have an artificial joint or heart valve. Do you recommend antibiotics before or after this procedure, and who decides?
• I have had a reaction to a local anesthetic, an antibiotic or a dressing in the past. How will you adjust for that?
• Roughly how long should I plan to be here, and may I leave the building between stages?
• Can I eat and drink during the day, and is it all right to bring a companion into the procedure room?
• Who will do the repair if the wound turns out to be large, and could that happen on a different day?
• What wound care do you want me to do at home, and what products do you prefer?
• How long should I avoid exercise, bending, lifting, swimming and shaving near the site?
• Will I be able to drive myself home, or should I arrange a lift?
• When are the stitches likely to come out, and when is my follow-up visit?
• How do I reach someone after hours if I have bleeding or another concern?
• What should I expect the scar to look like at one month, and at one year?

Do not be shy about asking a question twice. The answers about medicines, in particular, are worth hearing in writing, and a good team would rather repeat themselves than have you guess.

When to call your doctor

Most Mohs recoveries are uneventful, and the team will give you a number to call. Use it. The following signs, drawn from Mayo Clinic and Cleveland Clinic patient guidance, warrant a same-day call, and some warrant emergency care.

Call the team promptly for bleeding that soaks through the dressing and does not stop after firm, continuous pressure for the length of time they specified; for pain that increases rather than settles after the first day or two; for spreading redness, warmth, swelling or pus around the wound; for a fever or chills; for a foul smell from the dressing; for stitches that have come apart or a graft or flap that looks dusky, purple or black; or for numbness or weakness in the face that is new or that persists well beyond the expected wearing-off of the anesthetic.

Seek emergency help without waiting for a callback if bleeding is heavy and will not slow with pressure, if you develop chest pain, sudden breathlessness, facial drooping, slurred speech or weakness on one side of the body, or if you have signs of a severe allergic reaction such as swelling of the lips or tongue, difficulty breathing or widespread hives. Some of these are unrelated to the skin surgery itself but can occur in people who take heart or blood-thinning medicines, and they should never be sat out.

Between those extremes sits a large gray zone: a bruise that looks alarming, a scab that catches on a pillow, a wound that seems to be taking too long. Photograph it in good light and call. The team has seen thousands of healing wounds, and a two-minute conversation resolves most worries. The decision about whether you need to be seen, and what happens next, always rests with the people who treated you.

Frequently asked questions

Can I take my blood thinner before Mohs surgery?

In most cases yes, and you should not stop it unless the doctor who prescribes it has specifically agreed. Mayo Clinic and Cleveland Clinic both advise continuing anticoagulants and antiplatelet medicines through Mohs because the risk of a stroke or heart attack from a gap in treatment outweighs the risk of extra bleeding, which the surgical team can usually manage with pressure and cautery. Tell the team what you take and why.

How long does Mohs surgery take from arrival to leaving?

Plan for several hours, and accept that it may take most of a day. Each stage of tissue removal is followed by laboratory processing that Cleveland Clinic patient information puts at roughly an hour, and repair adds time at the end. One stage can be finished in a morning; several stages plus a flap or graft fill an afternoon. Bring food, entertainment and a warm layer, and do not schedule anything else.

What should I bring to Mohs surgery?

Bring a written list of every medicine, supplement and allergy, your pacemaker or implant card if you have one, something to read or watch, snacks and a drink, a sweater, reading glasses or hearing aids, and any medicine you take at a set time. Wear a front-opening shirt and skip make-up, moisturizer and jewelry near the site. Arrange someone to drive you home, since dressings near the eye or a long stressful day can make driving unsafe.

Do I need to fast before Mohs surgery?

Usually not. Mohs is performed under local anesthetic, so the fasting rules that apply to general anesthesia do not normally apply here. Most teams encourage a normal breakfast and snacks during the day, because arriving hungry raises the chance of feeling faint during the injection and makes the wait harder. People with diabetes should confirm meal and medicine timing with their team. Always follow any specific instruction you were given in writing.

I have a pacemaker. Is Mohs surgery safe for me?

Yes, with planning. Standard electrosurgery passes current through the body, which a pacemaker can misread as heart activity and a defibrillator can misread as a dangerous rhythm. Dermatologic surgeons routinely switch to bipolar or heat cautery, use short bursts away from the device, or coordinate with your cardiology team about settings and monitoring. Bring your device card and mention it on every form, even if the surgery is on your leg.

Which supplements should I mention before Mohs surgery?

Mention all of them, and specifically fish oil, vitamin E, ginkgo, garlic, ginger, turmeric and high-dose omega-3 products, which have mild effects on platelets or clotting. Also mention casual use of anti-inflammatory painkillers such as ibuprofen or naproxen. Teams often ask people to pause these for a short period before surgery, but the decision is theirs, and prescribed anti-inflammatories should be discussed with the prescriber rather than stopped independently.

What if I am allergic to lidocaine or other local anesthetics?

Describe exactly what happened and let the team interpret it. True allergy to the amide anesthetics used in Mohs is rare; many people who report one actually had palpitations or shakiness from the epinephrine mixed into the injection, which is a drug effect the surgeon can adjust for. If you have a documented true allergy, the team can select an alternative anesthetic or arrange allergy testing beforehand.

Do I need antibiotics before Mohs if I have an artificial joint or heart valve?

Not routinely. Mohs is performed on clean, uninfected skin, which current guideline thinking treats as low risk for seeding an implant. Some situations change that, such as a recent joint replacement, a graft, a wound in a high-bacteria area or a past prosthetic infection, and your surgeon may consult your orthopedic or cardiac team. State the facts on your questionnaire and let them decide; never take leftover antibiotics on your own.

What does recovery after Mohs surgery look like in the first two weeks?

Expect a firm dressing for the first day or so, then daily gentle cleansing, a thin layer of petroleum jelly and a fresh dressing. Bruising and swelling, especially around the eyes, are common in the first days. Mild pain is usual and often managed with acetaminophen on the team’s advice. Stitches on the face typically come out within about one to two weeks according to Cleveland Clinic, with body sites taking longer. Avoid heavy lifting, bending and swimming as instructed.

Does needing several stages mean the surgery is going badly?

No. Multiple stages mean the cancer extended further beneath the surface than was visible on top, which is common with basal and squamous cell carcinomas and is exactly why the layer-by-layer technique was chosen. Each additional stage removes a thin sliver from the precise spot where cells remained, sparing the healthy skin around it. Reconstruction is discussed only after the final slide is clear, so wound size is never predicted in advance.
