Preparing for Neck Cancer Treatment: Dental Review, Nutrition Planning and Fitness Tests

The appointment letter arrived with a list, and the list was not what she expected. Not surgery dates. Not the radiation schedule. A dentist. A dietitian. Something called a cardiopulmonary exercise test. She had braced for the cancer part and found herself, instead, being asked about her molars and how many stairs she could climb.

That reaction is common, and it is worth understanding why the list looks the way it does. Preparing for neck cancer treatment is less about the tumor and more about the neighborhood it lives in: the jaw, the salivary glands, the muscles that let you swallow, the heart and lungs that will carry you through weeks of therapy. Damage to any of those can be reduced, sometimes substantially, by work done before the first dose or the first incision.

This explainer walks through what the dental review checks, how nutrition planning works, what fitness tests are for, and what the following weeks tend to look like. Every decision along the way sits with your treating team; the goal here is that you walk into those conversations already fluent.

What does preparing for neck cancer treatment actually involve?

Head and neck cancers are a family of tumors that start in the mouth, throat, voice box, nose, sinuses or salivary glands; “neck cancer” in everyday speech usually means one of these, or cancer that has spread to lymph nodes in the neck. Treatment commonly involves surgery, radiation therapy, chemotherapy, or a combination, and each of those affects tissues that are hard to repair afterward (MedlinePlus).

Preparation, then, is a planned window between diagnosis and the first day of treatment. In most centers it runs alongside staging scans and the tumor board discussion, so it rarely adds much delay. Three strands run in parallel.

The dental strand exists because radiation to the jaw permanently reduces the bone’s blood supply and slows healing. A tooth pulled after radiation carries a real risk of osteoradionecrosis, a condition in which jawbone dies and fails to heal. Pulling or repairing risky teeth beforehand removes that hazard (NCI, Oral Complications PDQ).

The nutrition strand exists because treatment to the mouth and throat makes eating painful and difficult for weeks. People who start therapy already underweight, or who lose weight rapidly during it, tolerate treatment less well and are more likely to need unplanned breaks.

The fitness strand exists because surgery under general anesthesia, and long courses of chemotherapy and radiation, ask a great deal of the heart, lungs and muscles. Baseline tests tell the team how much reserve you have and whether anything needs attention first.

None of this is optional busywork. Each strand changes what the team can safely offer and how well you are likely to come through it. Think of it as building scaffolding before the renovation begins.

How serious is neck cancer? An honest, guideline-level answer

Seriousness depends on where the cancer started, how far it has grown, whether lymph nodes are involved, and, for cancers of the oropharynx (the back of the throat including tonsils and base of tongue), whether human papillomavirus (HPV) is the cause. HPV-related throat cancers behave differently from those linked to tobacco and alcohol and are considered as a separate group in staging systems (NCI head and neck fact sheet).

Stage is the shorthand doctors use. Early-stage disease is confined to the original site; later stages involve nearby structures or lymph nodes; the highest stage means spread to distant organs. The staging scans done during your preparation weeks, usually a CT or MRI of the neck and sometimes a PET-CT, are what turn a biopsy result into a stage.

What this article will not do is quote survival figures. Population statistics describe groups, not individuals, and the numbers vary enormously by subsite and cause. Your oncologist can give you a range that reflects your own scan results, and that conversation belongs with them.

What can be said in general terms: head and neck cancers are often treated with the intention of controlling the disease long-term, and many treatment plans combine methods to achieve that. The trade-off is that curative-intent treatment to this region is demanding on the body, which is precisely why the preparatory steps described here carry so much weight.

One more point of context. A lump in the neck is frequently the first sign of these cancers, because lymph nodes in the neck drain the mouth and throat. Persistent, painless swelling that lasts more than a few weeks warrants evaluation, but it is not a diagnosis, and many neck lumps turn out to be benign (NHS).

Why does a dental check before radiotherapy come first?

The dental review is usually the first preparatory appointment scheduled, and the reason is timing. Anything that needs pulling has to heal before radiation begins, so the dentist needs to see you early.

Radiation delivered to the head and neck passes through the jaws and salivary glands on its way to the tumor. Two lasting consequences follow. Salivary glands in the treatment field lose function, producing xerostomia, the medical term for chronic dry mouth. Saliva normally washes teeth and buffers acid; without it, decay advances quickly and in unusual places, often along the gumline. Meanwhile the irradiated bone becomes less able to heal from injury, including the injury of a tooth extraction (NCI, Oral Complications PDQ).

The dentist, ideally one experienced in oncology, examines every tooth and takes full X-rays. They are looking for deep decay, gum disease with bone loss, broken teeth, infected roots, and teeth that are partially erupted or impacted. Any tooth judged unlikely to survive the next several years is a candidate for removal now, while healing is normal.

Restorable problems are handled too: fillings replaced, sharp edges smoothed so they do not cut inflamed tissue, dentures adjusted to avoid pressure sores. The dentist will also take impressions for custom fluoride trays, soft plastic shields that hold high-strength fluoride against the teeth, which you will use daily for the rest of your life to slow radiation-related decay (NCI, Oral Complications PDQ).

If surgery rather than radiation is the main plan, the dental review still matters. Dental infection is a source of post-operative wound problems, and if radiation may follow surgery, the same rules apply.

People sometimes bristle at losing teeth for a cancer they cannot see. The logic is uncomfortable but sound: a tooth removed now heals in weeks; a tooth removed after radiation can become a wound that never closes.

Extractions, healing time and the two-week question

The most common question at the dental visit is how long extraction sockets need to heal before radiation can start. Guidance from the National Cancer Institute suggests that extractions should be completed with enough lead time for the gum to close over the socket, commonly around two weeks, though the exact interval is set by the oncology and dental teams together based on how many teeth are removed and how well you heal (NCI, Oral Complications PDQ).

That interval explains the scheduling scramble many people experience. The radiation oncologist wants to begin promptly; the dentist wants healing time; the two negotiate. Most programs manage this without meaningfully delaying treatment, because the staging scans and planning simulation take a similar amount of time anyway.

What the extraction visit is like: usually local anesthetic, sometimes sedation if many teeth are involved, and a procedure that resembles any other dental extraction. Dentists performing pre-radiation extractions often smooth the bone edges more carefully than usual and close the gum with stitches, because they know the tissue must be as calm as possible before radiation begins.

Healing afterward follows the ordinary pattern: soreness for a few days, a soft diet, salt-water rinses. Your dentist will check the sockets before clearing you for radiation.

Alongside extractions, expect a professional cleaning and detailed instruction in home care. Brushing with a soft brush after every meal, flossing daily, and using the fluoride trays become non-negotiable habits once salivary flow drops. Some people are also taught jaw-stretching exercises at this stage, because radiation to the chewing muscles can cause trismus, a stiffness that limits how wide the mouth opens. Starting the stretches before treatment, while the muscles are still supple, is easier than starting them afterward (NCI, Oral Complications PDQ).

If chemotherapy is part of the plan, the dentist also wants active infection cleared beforehand, since low white blood cell counts during chemotherapy make mouth infections harder to fight.

Head and neck cancer diet: what nutrition planning looks like before treatment

A dietitian is a regulated health professional trained in medical nutrition; in cancer care their job is to keep you fed when eating becomes difficult. In head and neck cancer, they are usually involved from the planning stage, and for good reason.

Many people arrive at diagnosis already having lost weight. A painful throat, a tumor that makes swallowing awkward, months of eating less, and in some cases heavy alcohol use, all contribute. Treatment then compounds the problem: radiation causes mucositis, painful inflammation of the lining of the mouth and throat, typically building over the first two to three weeks and peaking toward the end of the course (NCI, Oral Complications PDQ).

The first nutrition visit is an assessment. The dietitian weighs you, asks about recent weight change, reviews what you currently eat, and checks for swallowing difficulty. Blood tests ordered by the medical team often include albumin and other markers that reflect nutritional status.

The plan that follows aims to build reserve. If you have been losing weight, the immediate goal is to stop the slide and, where possible, regain some before treatment starts. Practical advice tends to center on energy-dense, protein-rich foods eaten in small frequent portions, fortifying ordinary meals rather than adopting a special regimen. Soft textures and moist foods are introduced early so they are familiar later.

There is a persistent myth that sugar feeds tumors and should be avoided during treatment. Mainstream nutrition guidance does not support restrictive diets during active cancer therapy; the greater danger by far is undernutrition, which weakens immunity, slows wound healing and can force treatment interruptions (Mayo Clinic).

The dietitian will also discuss what happens if swallowing fails. That is the moment to raise the feeding tube conversation, covered next, because it is far better to decide calmly in advance than urgently mid-treatment.

Feeding tubes: who is usually offered one and when

A gastrostomy tube is a soft tube placed through the abdominal wall directly into the stomach, used to deliver liquid nutrition when swallowing is unsafe or too painful. In head and neck cancer it is either placed before treatment as a precaution, or during treatment if eating becomes impossible.

Whether a tube is offered ahead of time depends on the treatment plan and your starting point. People receiving combined chemotherapy and radiation to the throat, those with significant weight loss already, and those whose tumor sits where swelling will block swallowing are commonly considered. People having surgery alone, or radiation to a small area away from the swallowing muscles, often do not need one.

Placement is a short procedure, usually done under sedation by a gastroenterologist or radiologist. The tube is uncomfortable for a few days and then most people forget it is there. It does not stop you eating by mouth; many people use it for part of their intake and continue swallowing whatever they can manage.

That last point matters more than it sounds. Speech and language therapists, who assess and treat swallowing disorders, encourage people to keep swallowing throughout treatment, even small amounts, because the muscles weaken quickly if unused. A feeding tube is a safety net, not a replacement for the swallowing muscles.

Tubes placed before treatment are usually removed once oral intake is reliably adequate again, typically in the months after treatment ends, though the timeline varies widely and is set by the dietitian and speech therapist based on your progress (NHS).

Some people decline a preventive tube and do well; others accept one and never need it heavily. The team will explain their reasoning for your situation. It is a genuine choice, and either answer can be right.

Fitness tests before surgery, radiation or chemotherapy

Baseline tests serve two purposes. They tell the team whether your body can safely tolerate the planned treatment, and they record where you started so changes can be spotted later.

Almost everyone has blood tests: a full blood count, kidney and liver function, and thyroid function, because radiation to the neck can damage the thyroid gland and cause hypothyroidism, an underactive thyroid, months or years later (NCI head and neck fact sheet). Some chemotherapy drugs are cleared by the kidneys, so kidney function influences drug choice; that decision is the oncologist’s.

An electrocardiogram, a tracing of the heart’s electrical rhythm, is standard before surgery under general anesthesia and before certain chemotherapy regimens. A hearing test is often performed before platinum-based chemotherapy, because this drug class can damage the inner ear and a baseline allows the team to detect early change.

For major surgery, especially operations that involve reconstruction with tissue moved from elsewhere in the body, the anesthetic team may request lung function tests or a cardiopulmonary exercise test. That test involves cycling or walking on a treadmill while breathing through a mask that measures oxygen use, and it gives an objective picture of how the heart and lungs cope under load.

This is also where prehabilitation comes in: structured exercise, breathing training and nutrition in the weeks before treatment to improve fitness going in. Evidence for prehabilitation is still developing across cancer types, and it is not yet standard everywhere, but the principle that fitter patients recover from surgery faster is well established. Even a daily walk that leaves you slightly breathless is worthwhile if your team agrees.

Smoking cessation belongs here too. Stopping smoking before treatment improves wound healing and reduces respiratory complications, and it appears to improve how well radiation works. Your team can refer you to cessation support; the earlier you stop, the more benefit accrues (NHS).

Who is usually asked to wait, and why a short delay can be safer

Nobody wants to hear that treatment will be pushed back. Yet there are situations where a deliberate pause of days to a couple of weeks reduces risk more than it adds.

The clearest example is dental healing. If several extractions are needed, radiation typically waits for the sockets to close, as discussed above. Beginning radiation over open wounds invites infection and poor healing in bone that will soon lose its capacity to repair.

Uncontrolled medical conditions are another reason. Very high blood sugar, poorly controlled blood pressure, an active chest infection or a recent heart event may prompt the anesthetic or oncology team to optimize those first. Surgery in particular is safer when these are settled.

Severe malnutrition may also justify a brief delay while the dietitian and, if needed, a feeding tube restore some reserve. A person who begins a seven-week radiation course already depleted has little margin for the weight loss that reliably follows.

Occasionally staging is the hold-up: a scan reveals something that needs a second biopsy, or the tumor board asks for an additional test before committing to a plan. That kind of delay is frustrating but it prevents treating the wrong problem.

Who is generally not asked to wait: people whose tumor is growing quickly, causing airway narrowing or bleeding, or where the team judges that the cancer’s pace outweighs the benefits of preparation. In those cases dental work may be shortened to essentials, nutrition support started in parallel, and treatment begun promptly.

The balance is always individual. If you are told to wait, ask what the wait achieves and what would change the plan. A good team can explain both, and hearing the reasoning usually makes the days pass more easily.

Preparing for neck cancer treatment: how the steps differ by treatment type

The three preparatory strands apply to everyone, but their emphasis shifts with the treatment planned. The table below summarizes typical patterns; your own list may differ, and the team’s version always takes precedence.

Preparation step	Surgery	Radiation therapy	Chemotherapy or chemoradiation
Dental review	Clear infection; plan for later radiation if likely	Essential; extractions healed before start; fluoride trays	Essential; infection cleared before immune suppression
Nutrition assessment	Build reserve for healing; plan for post-op feeding	Weight baseline; soft-diet strategies; tube discussion	Highest need; preventive tube often considered
Blood tests	Full count, kidney, liver, clotting	Full count, thyroid baseline	Full count, kidney and liver, hearing baseline
Heart and lung tests	ECG; lung or exercise tests for major reconstruction	Usually not required	ECG before certain drug classes
Swallowing and speech	Baseline assessment; voice planning if larynx involved	Exercises taught before start	Exercises taught before start
Lifestyle	Stop smoking; limit alcohol	Stop smoking; limit alcohol	Stop smoking; limit alcohol

Two patterns stand out. First, the dental review is never skipped when radiation is on the table, whether now or as a possible later step. Second, nutrition need rises steeply when chemotherapy is added to radiation, because the combination produces the most severe mouth and throat soreness (NCI, Oral Complications PDQ).

Reconstruction deserves a note. When surgeons remove part of the jaw or tongue, they often rebuild it using bone or skin from the forearm, leg or shoulder blade. Those operations are long and place real demands on the heart, which is why exercise testing appears in the surgery column and rarely elsewhere.

Where a plan includes more than one treatment, preparation covers all of them from the outset. Surgery followed by radiation, for instance, means the dental review happens before surgery even though radiation is weeks away, because extractions heal better in unoperated tissue.

What the first weeks of treatment usually look like

Once preparation is complete, the pattern of the following weeks depends on the treatment, but some features are common enough to describe.

Radiation therapy is typically delivered once a day, five days a week, for a course of around six to seven weeks, with each session lasting minutes (NHS). Before the first dose you attend a planning appointment where a custom mask is molded to your face and shoulders; the mask holds you still and is used at every session. The first week or two often feel deceptively easy. Soreness in the mouth and throat, thickened saliva, changes in taste and skin redness usually begin in the second or third week and build toward the end (NCI, Oral Complications PDQ). This is when the nutrition plan earns its keep and when many people start using a feeding tube if one was placed.

Chemotherapy given alongside radiation is usually delivered in cycles, often weekly or every three weeks, in a day unit. Nausea, tiredness and lowered blood counts are the expected effects; the team monitors blood tests between cycles.

Surgery follows a different arc. A hospital stay of days to a couple of weeks is usual for larger operations, longer if reconstruction is involved. Swallowing is often assessed before you are allowed to eat by mouth, and a temporary feeding tube through the nose or into the stomach is common. If the voice box was operated on, speech therapy begins early.

Across all three, weekly review appointments are standard. A nurse or doctor checks your weight, mouth, skin and blood results, and adjusts supportive care. Speak up early about pain or difficulty swallowing; problems caught in week two are far easier to manage than those reported in week five.

Fatigue deserves a mention because it surprises people. It accumulates through treatment and often peaks in the weeks after it ends, before slowly lifting.

Side effects of head and neck radiation in the long term, and how preparation changes them

Some effects of radiation to the head and neck fade over months; others are permanent. Knowing which is which explains why so much preparation is aimed at the mouth.

Dry mouth is the most common lasting effect. Salivary glands in the treatment field recover only partially, and many people manage some degree of xerostomia for life. Modern radiation techniques that shape the beam to spare the glands on one side have reduced its severity, but rarely eliminate it (Cleveland Clinic). The daily fluoride trays and meticulous brushing set up at the dental review are the direct response to this.

Radiation-related dental decay follows from dry mouth and can progress within months of treatment ending. Regular dental review, often every few months at first, catches it early.

Osteoradionecrosis, the failure of irradiated jawbone to heal, is the complication the pre-treatment extractions are designed to prevent. Any later dental surgery in the irradiated area requires special precautions, which is why you should tell every future dentist about your radiation history (NCI, Oral Complications PDQ).

Swallowing difficulty, or dysphagia, can persist because radiation scars the throat muscles. The exercises taught before treatment and continued through it are the main defense. Trismus, restricted jaw opening, behaves similarly.

Hypothyroidism develops in a proportion of people whose thyroid received radiation, sometimes years later, and is managed with thyroid hormone replacement once detected; the baseline thyroid test taken during preparation makes later changes obvious (NCI head and neck fact sheet). Lymphedema, swelling under the chin and in the neck from disrupted lymph drainage, is common after combined surgery and radiation and responds to specialist massage and exercises.

Taste changes, altered voice, skin changes and neck stiffness round out the list. None of this is intended to alarm; it is intended to show that the preparatory weeks are the moment when many of these effects can be softened.

What people often get wrong about preparing for neck cancer treatment

“The dentist is delaying my cancer treatment.” The dental review usually runs in parallel with staging scans and radiation planning, which take a similar length of time. Where it does add days, the trade-off is avoiding a jawbone wound that may never heal.

“I should eat clean and cut sugar to starve the cancer.” There is no mainstream evidence that dietary restriction shrinks head and neck tumors, and undernutrition during treatment is a well-documented cause of complications and interruptions. Dietitians in cancer care typically encourage more calories and protein, not fewer (Mayo Clinic).

“A feeding tube means giving up on eating.” The opposite is closer to the truth. A tube removes the pressure to meet every calorie by mouth, which lets you keep swallowing small comfortable amounts and preserve the muscles for later.

“Once I’m fit for treatment, the fitness tests are done.” Baseline tests are also a reference point. Thyroid and hearing tests taken before treatment allow the team to spot changes years later.

“Radiation side effects show up on day one.” Mouth soreness and skin changes typically build over the second and third weeks and peak toward the end of the course, with some effects continuing to worsen briefly after the final session (NCI, Oral Complications PDQ).

“Supplements will protect my mouth or boost my immune system.” High-dose antioxidant supplements during radiation are a particular concern because of theoretical interference with how radiation damages tumor cells. Tell your team about anything you take; the evidence for most over-the-counter products in this setting is absent or uncertain (NIH Office of Dietary Supplements).

“It’s too late to stop smoking now.” Stopping at any point before or during treatment improves healing and reduces complications, and the benefit begins within weeks (NHS).

Questions to ask your care team before treatment begins

Consultations move fast and the vocabulary is unfamiliar. Bringing a written list, and a second person to take notes, changes the quality of what you take home. These are questions that patients and clinicians tend to find most useful at the preparation stage.

• Which treatments are you recommending, in what order, and what is the intention of each?
• Which of my teeth, if any, need removing, and how long before treatment must that be done?
• Will my salivary glands be in the radiation field, and can any of them be spared?
• Should I have a feeding tube placed before treatment, and what would change your advice?
• Who is my dietitian and my speech and language therapist, and when will I see them?
• Which swallowing and jaw exercises should I start now?
• What baseline tests are you ordering and what will they be compared against later?
• If surgery involves reconstruction, where will the tissue come from and how will that affect recovery?
• How will my voice and swallowing be different afterward, and for how long?
• Which side effects are likely to be permanent, and what will we do about them?
• Whom do I call, day or night, if something worries me during treatment?
• Is there a clinical trial relevant to my situation?
• Can you help me stop smoking or reduce alcohol before we start?

A follow-up point worth raising: ask the team to write down the plan, including the sequence of treatments and the expected timeline. Written plans reduce the misunderstandings that arise when several specialists are involved and information reaches you piecemeal.

If English is not your first language, request an interpreter for each appointment; hospital interpreters are trained in medical vocabulary in a way family members usually are not. And if anything in the plan does not make sense to you, say so. Clinicians would far rather explain twice than discover confusion mid-treatment.

When to call your doctor

During the preparatory weeks and once treatment starts, some symptoms need prompt attention rather than a wait for the next scheduled visit. Your team will give you a direct number; use it. The following are widely agreed red flags.

Call the same day, or seek emergency care, if you notice:

• Difficulty breathing, noisy breathing, or a sense that your airway is narrowing.
• Bleeding from the mouth, nose or throat that does not stop within a few minutes of gentle pressure, or that you are coughing or vomiting up.
• Fever, chills or shaking, particularly during chemotherapy, when low white cell counts can turn a minor infection into a serious one within hours.
• Inability to swallow liquids or your own saliva.
• Sudden severe pain, swelling or spreading redness in the face, neck or jaw.
• Confusion, drowsiness or fainting.

Call within a day or two if you notice:

• Weight loss of more than a few pounds in a week, or being unable to eat or drink normally for more than a day.
• A sore or extraction site in the mouth that is not healing, or exposed bone.
• New or worsening pain that your prescribed medicines are not controlling.
• Vomiting or diarrhea lasting more than a day.
• Leakage, redness or pain around a feeding tube site.
• Persistent hoarseness or a change in voice that is new since your last review.

None of these lists is exhaustive. The guiding principle used in cancer care is simple: if something feels wrong and you are unsure whether it matters, calling is the right answer. Teams expect these calls and plan for them. Reporting a problem early almost always means a smaller intervention than reporting it late, and it never means you are being a nuisance (MedlinePlus).

Frequently asked questions

How serious is neck cancer?

Seriousness depends on the site, stage, lymph node involvement and, for throat cancers, whether HPV is the cause. Early-stage disease confined to one site behaves very differently from cancer that has spread to distant organs. Population survival figures describe groups rather than individuals, so the meaningful answer comes from your oncologist once staging scans are complete. Many head and neck cancers are treated with the aim of long-term control.

Why do I need a dental check before radiotherapy?

Radiation to the head and neck permanently reduces saliva and the jawbone’s ability to heal. Teeth extracted after radiation carry a risk of osteoradionecrosis, in which bone dies and fails to heal. Removing or repairing risky teeth beforehand avoids that, and the dentist also fits fluoride trays to protect against the rapid decay that dry mouth causes.

What does a head and neck cancer diet involve before treatment?

It usually means building reserve rather than restricting anything. A dietitian assesses your weight, recent changes and swallowing, then advises energy-dense, protein-rich foods in small frequent portions. Soft, moist textures are introduced early so they are familiar once mouth soreness begins. Restrictive or sugar-free regimens are not supported by evidence and risk undernutrition, which is the greater danger during treatment.

What are the potential long-term side effects of head and neck radiation therapy?

The most common lasting effects are dry mouth, increased dental decay, swallowing difficulty, jaw stiffness, taste changes and an underactive thyroid. Osteoradionecrosis of the jaw can occur after later dental surgery. Lymphedema, swelling under the chin and neck, is common after combined surgery and radiation. Many of these can be reduced by pre-treatment dental care, swallowing exercises and beam-shaping techniques that spare salivary glands.

What are the symptoms of early-stage cancer with lymph nodes in the neck?

A persistent, usually painless lump in the neck lasting more than a few weeks is the most common presentation, sometimes alongside a sore throat, hoarseness, mouth ulcer or ear pain on one side. These symptoms have many benign causes and cannot be self-diagnosed; a clinician will examine you and may arrange imaging or a needle biopsy. Seek evaluation for any neck swelling that does not settle.

What do cancer patients need the most during head and neck treatment?

Clinically, adequate nutrition and prompt management of mouth pain are what keep treatment on schedule. Practically, people consistently report needing clear written information, one named contact for questions, help with transport to daily radiation, and someone to attend appointments with them. Emotional support, whether from family, a counselor or a peer group, matters as much as any test.

Will I definitely need a feeding tube?

No. Tubes are commonly offered before combined chemoradiation to the throat or when significant weight loss already exists, but many people having surgery alone or radiation to a small area never need one. The decision is made with your dietitian and oncologist based on your treatment plan, and a tube placed as a precaution is removed once you are eating reliably again.

What fitness tests are done before head and neck cancer surgery?

Blood tests, an electrocardiogram to check heart rhythm, and for major reconstructive operations sometimes lung function tests or a cardiopulmonary exercise test on a bike or treadmill. These assess whether you can safely tolerate a long anesthetic and record a baseline. Chemotherapy plans may add a hearing test, since platinum-based drugs can affect the inner ear.

How long does preparation take before treatment starts?

Usually a few weeks, running alongside staging scans and radiation planning. Dental extractions are commonly given around two weeks to heal, and planning appointments for radiation take a similar interval, so the dental work rarely adds much delay. Teams shorten preparation to essentials when a tumor is growing quickly or causing airway or bleeding problems.

Can I take vitamins or supplements during radiation?

Tell your team about everything you take before deciding. High-dose antioxidant supplements are a particular concern during radiation because of possible interference with how it damages tumor cells, and evidence for most products in this setting is absent or uncertain. A dietitian can usually meet nutritional needs through food or prescribed nutrition products instead.
