Laryngeal Cancer Treatment: What to Expect Over Time

Advanced laryngeal (voice box) cancer is treated along one of several tracks. Some tracks try to keep the voice box with radiation and chemotherapy, and others remove it with surgery. The track recommended for each person depends on the stage and extent of the cancer, how well the larynx still works, the person's overall health, and the person's own priorities.

About these pages

This page describes what usually happens, step by step, after a diagnosis of advanced cancer of the larynx (see throat cancers and larynx tumors). It covers the steps every treatment track shares, explains how a track is chosen, and links to a separate timeline page for each track. Every timeline uses the same time scale, starting at the biopsy that confirms the cancer, so the tracks can be compared side by side.

These pages cover advanced (stage III and IV) cancer. Early (stage I and II) laryngeal cancer, which is usually treated with radiation alone or with a smaller operation that keeps the voice box, has its own early laryngeal cancer treatment timelines page.

The times shown are typical ranges. Every person is different, and a care team may do things in a different order or on a different schedule. These pages are a map rather than a rulebook.

What "larynx" and "advanced" mean

The larynx, or voice box, sits at the top of the windpipe in the front of the neck. It holds the vocal cords, protects the airway during swallowing, and lets air pass to and from the lungs (see voice). It has three parts: the area above the vocal cords (supraglottis), the vocal cords themselves (glottis), and the area just below them (subglottis). Almost all laryngeal cancers are squamous cell carcinoma, which starts in the lining of the larynx (see squamous cell carcinoma of the mouth and throat).

"Advanced" usually means stage III or stage IV. The tumor may have stopped a vocal cord from moving, grown into the deeper spaces of the larynx or the cartilage around it, grown through the cartilage into the neck, or spread to lymph nodes in the neck. In most cases it has not spread to distant parts of the body and is still treated with the goal of cure.

How laryngeal cancer differs from other throat cancers

Unlike many throat (oropharyngeal) cancers, laryngeal cancers are rarely caused by HPV (human papillomavirus), and HPV testing does not change how laryngeal cancer is staged or treated. Laryngeal cancer is most strongly linked to smoking, and alcohol adds to the risk.

What sets laryngeal cancer apart is the voice box itself. For many advanced cancers there are two broad approaches with similar survival: treatment that tries to keep the larynx (larynx preservation), with a laryngectomy kept in reserve if the cancer is not controlled, and surgery that removes the larynx first. For cancers that have destroyed the cartilage or grown outside the larynx, or a larynx that no longer works well, removing the larynx is linked with better survival. A larynx that is kept only counts as a success if it still works: needing a tracheostomy or a feeding tube for the long term after treatment is not the goal. Choosing between these approaches, natural voice versus the most durable control of the cancer, is the biggest decision in the plan.

The roadmap at a glance

Most people move through eight phases:

1. Biopsy: confirming the diagnosis (about 1 week)

2. Scans and getting ready: imaging, dental, nutrition, speech, swallowing and hearing (about 1 to 2 weeks)

3. Meeting the team and the tumor board (within the first 2 to 4 weeks)

4. Main treatment: surgery, chemoradiation, or chemotherapy followed by radiation (about 6 to 7 weeks for radiation, and longer when chemotherapy comes first)

5. Recovery and checking the response (about 2 to 3 months)

6. Added treatment, if needed: radiation after surgery, or surgery if cancer remains after radiation

7. Rehabilitation and survivorship, including voice and swallowing (months)

8. Follow-up (years)

A common goal is to begin treatment within about 3 to 4 weeks of diagnosis. Starting the first treatment sooner, generally within 30 days and without delays beyond 6 to 8 weeks, is linked with better outcomes, which is why the early steps move quickly.

Step 1: The biopsy (about 1 week)

A biopsy removes a small piece of the tumor so a pathologist can confirm cancer under the microscope (see understanding pathology results). The timelines count from this biopsy as week 0.

• Scope exam in the office: a thin flexible camera passed through the nose (fiberoptic laryngoscopy) shows the tumor, whether the vocal cords move, and how open the airway is. A vocal cord that no longer moves is an important finding for staging. At some centers, a biopsy can be taken through the scope in the office, which can shorten the time to treatment.

• Biopsy in the operating room (direct laryngoscopy): at most centers, advanced laryngeal biopsies are taken under a short general anesthetic as day surgery, which also lets the surgeon map the full extent of the tumor and look for a second tumor. Scans are ideally done before this procedure, because the swelling it causes can make scans harder to read.

• Needle biopsy of a neck lump: if a lymph node is swollen, a thin needle samples it (fine needle aspiration), sometimes guided by ultrasound.

When surgery is planned, the tumor is also tested for a protein called PD-L1, which can make an immunotherapy option available. HPV testing is not routinely done for laryngeal cancer.

Breathing comes first. A large laryngeal tumor can narrow the airway. When breathing is already difficult, a breathing tube in the neck (tracheostomy) may be placed before or at the time of the biopsy. A tumor that needs a tracheostomy before treatment also weighs on which track is chosen.

Step 2: Scans and getting ready (about 1 to 2 weeks)

Before treatment, the care team needs a complete picture of where the cancer is, and a plan to protect health through treatment. These steps often happen at the same time.

Scans of the neck and chest

• CT scan with contrast of the neck: the main scan for showing how deeply the tumor has grown and whether it has reached or gone through the cartilage of the larynx. MRI is added when the CT is unclear about the cartilage or nerves.

• PET-CT scan: preferred for advanced cancer to check the neck lymph nodes and the whole body, especially the lungs, for spread. It changes the treatment plan in about 1 in 5 people. When a PET-CT is not done, a CT of the chest is done instead. A PET scan takes about 45 to 90 minutes and requires fasting.

Appointments that protect health through treatment

• Airway, voice and swallowing evaluation: everyone with advanced laryngeal cancer has a baseline check of breathing, voice and swallowing, often with an X-ray swallow study or a scope swallow study (see swallow evaluations), because food or liquid can enter the airway without causing a cough. How well the larynx works now helps decide whether keeping it is likely to succeed. Swallowing exercises started before treatment improve swallowing afterward. When surgery to remove the larynx is possible, this visit also covers the ways speech can be restored afterward, which helps people adjust.

• Dental evaluation, early: if radiation is likely, teeth in poor condition are treated or removed at least 2 weeks before radiation starts, to lower the risk of a serious long-term jaw problem called osteoradionecrosis. Dental work is a common reason treatment starts later than planned, so this visit is scheduled promptly.

• Nutrition: a dietitian helps keep weight and strength up. A feeding tube is not placed for everyone ahead of time, but it is often planned for people who have already lost a lot of weight, have trouble swallowing or a narrowed airway; otherwise one is placed during treatment if needed.

• Hearing test: when the chemotherapy drug cisplatin may be used, a baseline hearing test is done, because cisplatin affects hearing in many people. Treatment is not delayed if this test cannot be done in time.

• Breathing and fitness: lung function is checked when a partial laryngectomy is being considered (see pulmonary function testing), along with overall fitness, since many people with laryngeal cancer have smoked and may also have lung or heart disease.

• Other steps: support to stop smoking and limit alcohol, a hepatitis B blood test when chemotherapy is planned, and screening for distress, with attention to emotional well-being and support at home (see cancer information resources). In laryngeal cancer, stopping smoking after diagnosis is linked with a better response to treatment, a better chance of keeping the larynx, and longer survival.

At some centers, these appointments are combined into a single-day clinic. Either way, people usually have several appointments over 1 to 2 weeks.

Step 3: Meeting the team and the tumor board (within the first 2 to 4 weeks)

Advanced laryngeal cancer is treated by a team rather than a single doctor. The team often includes a head and neck surgeon, a radiation oncologist, a medical oncologist, a radiologist, a pathologist, a speech-language pathologist, a dietitian, a dentist, an audiologist, and nurses, social workers and support staff. Treatment at an experienced, high-volume center is linked with better results, and a tumor board review changes the plan for about 1 in 10 to 1 in 4 people.

Before treatment begins, the whole team reviews the case together at a multidisciplinary tumor board and agrees on a recommendation. For advanced laryngeal cancer, the recommendation often lays out more than one reasonable track, and the person's own priorities carry real weight in the choice.

The two main approaches

Larynx preservation (keeping the voice box)

• Chemoradiation: radiation 5 days a week for about 7 weeks, with chemotherapy (usually cisplatin) given during radiation. This is the approach most often used to keep the larynx.

• Chemotherapy first (induction chemotherapy): several cycles of chemotherapy are given first. If the tumor shrinks well, radiation (often with chemotherapy) follows. If it does not, surgery to remove the larynx follows instead.

• Radiation alone, or radiation with a different drug, for people whose health does not allow cisplatin. Other drugs given with radiation work less well than cisplatin, so they are kept for people who cannot receive it.

• Salvage surgery: when cancer remains or returns in the larynx after radiation, which happens for about 1 in 6 to 1 in 3 people, a laryngectomy can still offer a cure. The larynx has one of the best salvage success rates in the head and neck. Healing is slower after radiation, and a leak from the throat to the skin is more common, so a flap of healthy tissue is often used to strengthen the repair.

• A larynx that is kept is not always a larynx that works well. Some people have lasting trouble swallowing or breathing after radiation. A larynx that no longer protects the airway may later need to be removed.

Surgery first

• Total laryngectomy removes the whole larynx. The windpipe is brought out to an opening in the front of the neck (a stoma), and breathing happens through that opening for life. The mouth and nose are no longer connected to the lungs, so the sense of smell is reduced and the stoma needs daily care, including moistening the air and clearing mucus. Eating and swallowing go through the throat as before, and swallowing is often better after laryngectomy than after chemoradiation. The hospital stay is commonly about 2 to 3 weeks, and some people go to a rehabilitation facility before going home.

• Neck dissection removes lymph nodes on one or both sides of the neck, often at the same operation. Part or all of the thyroid gland is often removed as well.

• Partial laryngectomy: for some carefully selected advanced cancers, part of the larynx can be removed through the mouth or the neck while keeping a voice and normal breathing. This is less common and depends on the tumor's exact location.

• Speaking again: most people can speak after a total laryngectomy. The most common method, and the one with the best voice quality, is a small one-way valve placed between the windpipe and the esophagus (a tracheoesophageal voice prosthesis), often at the same operation, with speaking starting about 2 to 3 weeks later. Covering the stoma sends air through the valve and produces a voice. A hand-held electrolarynx, held against the neck, can be used right away and is often the first method used. Fewer people learn esophageal speech, which is the hardest to master.

Choosing a treatment track

What the recommendation is based on

The tumor board's recommendation weighs several factors together:

• Stage and extent of the cancer: whether the tumor has grown through the cartilage or outside the larynx, its size, and how many neck lymph nodes are involved. When the cartilage has been destroyed, removing the larynx is usually the main recommendation, and many lymph nodes in the neck can also tilt the choice toward surgery.

• How well the larynx works now: a larynx that already causes choking on liquids, food entering the airway, or the need for a tracheostomy or feeding tube is less likely to work well after radiation.

• Overall health: other medical conditions, fitness for surgery and anesthesia, how active a person is day to day, lung function, and nutrition. Kidney function, hearing and other conditions decide whether cisplatin can be given safely.

• The PD-L1 marker: a positive result can make the immunotherapy track an option. Because that track starts before surgery, it is discussed early.

• Smoking and alcohol use, which affect both healing and the outlook.

• The person's own priorities: keeping the natural voice, the time and side effects of each treatment, how close the person lives to the treatment center, and how each track fits the person's life.

The treatment tracks

The chart shows which track usually follows in each situation. Each track has its own timeline page:

1. Laryngectomy alone: when the pathology report after surgery shows clear margins, few or no involved lymph nodes and no other high-risk features, no further treatment may be needed, only regular follow-up. Radiation is sometimes still offered in this situation.

2. Laryngectomy followed by radiation: the most common surgical track for advanced cancer, used when the report shows features such as a large tumor, growth through the cartilage, several involved lymph nodes, cancer along nerves or in small vessels, close margins, or spread below the vocal cords. Radiation usually runs 5 days a week for about 6 to 6.5 weeks and ideally starts within 6 weeks of surgery.

3. Laryngectomy followed by chemoradiation: when cancer is found at the margin or has grown outside a lymph node. Adding chemotherapy, usually cisplatin, to radiation improves tumor control and survival for these features.

4. Chemoradiation (larynx preservation): radiation with cisplatin, aimed at keeping the voice box, most often for cancers that have not destroyed the cartilage and a larynx that still works. Of the larynx-keeping approaches, it keeps the larynx most often over the long term. A laryngectomy is held in reserve.

5. Chemotherapy first, then radiation or surgery: 2 or 3 cycles of chemotherapy test how the cancer responds. A good response leads to radiation, and a poor response, seen in about 1 in 7 people, leads to laryngectomy.

6. Immunotherapy, surgery and radiation: for some advanced cancers that test PD-L1-positive and are treated with surgery, the immunotherapy drug pembrolizumab is given before surgery and continued afterward with radiation (with cisplatin when high-risk features are present). In a large 2025 study that included laryngeal cancer, this approach lengthened the time people lived without the cancer returning. Adding immunotherapy to chemoradiation without surgery has not improved results.

Reading the timelines

Each track page has a timeline with rows for diagnosis and planning, treatment, side effects and healing, quality of life, check-ups and scans, long-term care, and survival. Teal words in each timeline are links to related pages on this site.

The quality-of-life row shows average scores that patients reported in published studies, for overall quality of life, swallowing, speech and mood. Scores run from 0 to 100, higher is better, and a change of about 10 points is generally noticeable. These averages describe groups of people, not what any one person will feel. The questionnaires behind the scores are described on the quality-of-life questionnaires page.

What radiation and chemoradiation feel like

Side effects build gradually and are usually worst in the last week or two of treatment and for a couple of weeks afterward, then improve:

• Throat soreness (mucositis), which affects nearly everyone, can make swallowing painful, and often needs strong pain medicine

• Hoarseness and swelling of the larynx, which can last for months

• Dry mouth and taste changes

• Difficulty swallowing; about half of people need a feeding tube for a while, and many need IV fluids

• Tiredness, skin changes over the neck, and weight loss, on average about 15 pounds (7 kg); about a third need a hospital stay for supportive care

• With cisplatin: possible effects on hearing (ringing or hearing loss in about 1 in 3), the kidneys, nerves and blood counts, which are checked closely

Soreness usually peaks in the week or two after radiation ends. Keeping some eating and drinking by mouth during treatment helps long-term swallowing. The dietitian and speech-language pathologist stay closely involved through this phase.

Rehabilitation and the first year

Recovery of function is gradual and uneven.

• After larynx preservation, the voice is often rough for months and settles over the first year. Swallowing is usually at its lowest about 3 months after treatment and then improves, with clear gains between 3 and 6 months. By 1 year, only about 1 in 25 people still depend on a feeding tube. Swallowing exercises started before and during radiation make a difference, and they still help years later.

• After a total laryngectomy, a feeding tube through the nose is used for the first 1 to 2 weeks, and eating by mouth usually starts after a swallow test shows the throat has healed. The main early problem to watch for is a leak from the throat to the skin of the neck (a fistula), which affects about 1 in 10 to 1 in 4 people, usually appears around day 12, and most often heals with time. Speaking with a voice prosthesis usually starts about 2 to 3 weeks after surgery. A speech-language pathologist teaches use of the voice prosthesis or electrolarynx, care of the stoma, and use of a stoma filter that warms and moistens the air (a heat and moisture exchanger). Speech becomes steadier over 3 to 6 months. Voice prostheses are changed every few months as they wear.

• Feeding tube: most people who need one have it removed within a few months as eating by mouth recovers; after laryngectomy, about 85 in 100 have it out by 1 year.

• Return to work varies widely, from a few months to closer to 6 months or more after radiation or chemoradiation.

Living well after treatment

The care team watches for and helps manage these long-term effects:

• Swallowing: long-term swallowing trouble is common after advanced head and neck cancer. Narrowing of the throat, which is most common around 6 months, can occur after laryngectomy or radiation and is often treated by gently stretching it (dilation). Stiffness from radiation can slowly worsen swallowing years later.

• Pneumonia from food or liquid entering the airway: after chemoradiation for laryngeal cancer, about 1 in 4 people have this at some point, often without coughing. New coughing with meals, fevers or chest infections are reported to the care team.

• Stoma and breathing after laryngectomy: daily stoma care, a stoma filter, and a stoma cover in the shower. Emergency responders breathe for a person with a laryngectomy through the neck, not the mouth, so many people carry a medical card or bracelet. Support groups for people who have had a laryngectomy are a valuable resource.

• Underactive thyroid: the most common hormone problem after treatment, especially after laryngeal cancer; about 1 in 5 people have it by 5 years, often starting around 2 years after treatment. A TSH blood test every 6 to 12 months for the first 3 years after treatment checks for hypothyroidism, and treatment is a daily pill.

• Dry mouth and dental health: dry mouth is common after radiation. Dental visits and possible fluoride treatments help prevent tooth decay and jaw bone problems (osteoradionecrosis).

• Lymphedema: swelling inside and outside the neck affects most people in the first months and is treatable with specialized therapy, best started early.

• Hearing: ringing or hearing loss after cisplatin can last, and hearing tests continue as needed.

• Neck arteries: years after neck radiation, the carotid arteries can narrow. An ultrasound of the neck arteries every few years may be considered, alongside care for blood pressure and cholesterol.

• Emotional health: depression and anxiety are more common after head and neck cancer than after most other cancers, and changes in voice and breathing can affect relationships and work. They are treatable, and regular screening and emotional support are a standard part of care. Voice rehabilitation also lowers anxiety and depression.

• New cancers: laryngeal cancer survivors have one of the highest chances of any cancer survivors of a second cancer, most often of the lung, head and neck, or esophagus. This is a major reason for lifelong follow-up, yearly low-dose CT lung screening for people who qualify, and staying off tobacco and limiting alcohol.

Within the first year, the care team often provides a written survivorship care plan that covers these items.

Follow-up schedule

Regular check-ups find problems early. Most returns of laryngeal cancer happen in the first 2 years, and most are first noticed by the patient, so new or changing symptoms are reported between visits rather than saved for the next one. The follow-up clock starts at the end of treatment, so the first year runs from the end of treatment until 1 year later. A common schedule, based on national cancer guidelines:

Each visit includes a full head and neck exam, usually with a small flexible camera (fiberoptic laryngoscopy) when the larynx has been kept. A PET-CT scan no earlier than 12 weeks after radiation shows whether any cancer remains and sets a new baseline (earlier scans are often falsely worrying). After surgery, a new baseline CT or MRI is done within about 3 to 4 months. After that, scans are usually done to check a symptom or a finding rather than on a fixed routine. People who smoked may be offered yearly low-dose CT lung screening.

Symptoms that are reported to the care team promptly include new or worsening hoarseness, noisy or difficult breathing, a new lump in the neck, worsening trouble swallowing, coughing or choking with meals, ear pain, coughing up blood, unexplained weight loss, or a change around the stoma.

Survival

About 54 in 100 people with stage III laryngeal cancer, and about 45 to 54 in 100 with stage IV, are alive 5 years after diagnosis (overall survival, which counts deaths from any cause, from large national cancer registries). These figures describe large groups treated in many ways, not any one person. In the large larynx preservation studies, survival at 5 years was similar whether people had chemoradiation, chemotherapy first, or radiation alone, and for cancers that have destroyed the cartilage, laryngectomy is linked with better survival. When cancer returns in the larynx after radiation, salvage laryngectomy still cures many people: about 42 to 48 in 100 are alive at 5 years.

Questions people often ask the care team

• What is my exact stage, and has the cancer reached the cartilage?

• Is keeping my voice box a reasonable option for me, and how likely is it to work well afterward?

• If I choose larynx preservation, what happens if the cancer is not fully controlled?

• If my larynx is removed, how will I speak, and when can a voice prosthesis be placed?

• Will I need a tracheostomy or a feeding tube, and for how long?

• Does my tumor's PD-L1 result make immunotherapy an option?

• What support is available for quitting smoking, nutrition and emotional health?
