Laryngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the larynx.
The larynx is a part of the throat, between the base of the tongue and the trachea. The larynx contains the vocal cords, which vibrate and make sound when air is directed against them. The sound echoes through the pharynx, mouth, and nose to make a person's voice.
There are three main parts of the larynx:
Laryngeal cancer forms in the tissues of the larynx (area of the throat that contains the vocal cords). The larynx includes the supraglottis, glottis (vocal cords), and subglottis. The cancer may spread to nearby tissues or to the thyroid, trachea, or esophagus. It may also spread to the lymph nodes in the neck, the carotid artery, the upper part of the spinal column, the chest, and to other parts of the body (not shown).
Most laryngeal cancers form in squamous cells, the thin, flat cells lining the inside of the larynx.
Laryngeal cancer is a type of head and neck cancer.
Use of tobacco products and drinking too much alcohol can affect the risk of laryngeal cancer.
Anything that increases a person's chance of getting a disease is called a risk factor. Not every person with one or more of these risk factors will develop laryngeal cancer, and it will develop in people who don't have any known risk factors. Talk with your doctor if you think you may be at risk.
Signs and symptoms of laryngeal cancer include a sore throat and ear pain.
These and other signs and symptoms may be caused by laryngeal cancer or by other conditions. Check with your doctor if you have any of the following:
Tests that examine the throat and neck are used to help diagnose and stage laryngeal cancer.
In addition to asking about your personal and family health history, your doctor may perform the following tests and procedures:
Certain factors affect prognosis (chance of recovery) and treatment options.
Prognosis depends on the following:
Treatment options depend on the following:
Smoking tobacco and drinking alcohol decrease the effectiveness of treatment for laryngeal cancer. Patients with laryngeal cancer who continue to smoke and drink are less likely to be cured and more likely to develop a second tumor. After treatment for laryngeal cancer, frequent and careful follow-up is important.
After laryngeal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the larynx or to other parts of the body.
The process used to find out if cancer has spread within the larynx or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage of the disease in order to plan treatment. The results of some of the tests used to diagnose laryngeal cancer are often also used to stage the disease.
There are three ways that cancer spreads in the body.
Cancer can spread through tissue, the lymph system, and the blood:
Cancer may spread from where it began to other parts of the body.
When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if laryngeal cancer spreads to the lung, the cancer cells in the lung are actually laryngeal cancer cells. The disease is metastatic laryngeal cancer, not lung cancer.
The following stages are used for laryngeal cancer:
Stage 0 (Carcinoma in Situ)
In stage 0, abnormal cells are found in the lining of the larynx. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.
In stage I, cancer has formed in the supraglottis, glottis, or subglottis area of the larynx:
In stage II, cancer has formed in the supraglottis, glottis, or subglottis area of the larynx:
In stage III, cancer has formed in the supraglottis, glottis, or subglottis area of the larynx:
Tumor sizes are often measured in centimeters (cm) or inches. Common food items that can be used to show tumor size in cm include: a pea (1 cm), a peanut (2 cm), a grape (3 cm), a walnut (4 cm), a lime (5 cm or 2 inches), an egg (6 cm), a peach (7 cm), and a grapefruit (10 cm or 4 inches).
In stage III cancer of the supraglottis:
In stage III cancer of the glottis:
In stage III cancer of the subglottis:
Stage IV is divided into stage IVA, stage IVB, and stage IVC. Each substage is the same for cancer in the supraglottis, glottis, or subglottis.
After surgery, the stage of the cancer may change and more treatment may be needed.
If the cancer is removed by surgery, a pathologist will examine a sample of the cancer tissue under a microscope. Sometimes, the pathologist's review will result in a change to the stage of the cancer and more treatment after surgery.
Laryngeal cancer can recur (come back) after it has been treated.
The cancer may come back in the larynx or in other parts of the body, such as lungs, liver, or bone. It is most likely to come back in the first 2 to 3 years.
There are different types of treatment for patients with laryngeal cancer.
Different types of treatment are available for patients with laryngeal cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
The following types of treatment are used:
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer.
External-beam radiation therapy of the head and neck. A machine is used to aim high-energy radiation at the cancer. The machine can rotate around the patient, delivering radiation from many different angles to provide highly conformal treatment. A mesh mask helps keep the patient's head and neck from moving during treatment. Small ink marks are put on the mask. The ink marks are used to line up the radiation machine in the same position before each treatment.
Radiation therapy may work better in patients who have stopped smoking before beginning treatment. External radiation therapy to the thyroid or the pituitary gland may change the way the thyroid gland works. A blood test to check the thyroid hormone level in the body may be done before and after therapy to make sure the thyroid gland is working properly.
Hyperfractionated radiation therapy may be used to treat laryngeal cancer. Hyperfractionated radiation therapy is radiation treatment in which a smaller than usual total daily dose of radiation is divided into two doses and the treatments are given twice a day. Hyperfractionated radiation therapy is given over the same period of time (days or weeks) as standard radiation therapy. New types of radiation therapy are being studied in the treatment of laryngeal cancer.
Surgery (removing the cancer in an operation) is a common treatment for all stages of laryngeal cancer. The following surgical procedures may be used:
After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy).
For more information, see Drugs Approved for Head and Neck Cancer. Laryngeal cancer is a type of head and neck cancer.
Immunotherapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This cancer treatment is a type of biologic therapy.
Immune checkpoint inhibitor. Checkpoint proteins, such as PD-L1 on tumor cells and PD-1 on T cells, help keep immune responses in check. The binding of PD-L1 to PD-1 keeps T cells from killing tumor cells in the body (left panel). Blocking the binding of PD-L1 to PD-1 with an immune checkpoint inhibitor (anti-PD-L1 or anti-PD-1) allows the T cells to kill tumor cells (right panel).
New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.
Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells.
Radiosensitizers are drugs that make tumor cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more tumor cells.
Treatment for laryngeal cancer may cause side effects.
For information about side effects caused by treatment for cancer, see our Side Effects page.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. Information about clinical trials supported by NCI can be found on NCI's clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
For information about the treatments listed below, see the Treatment Option Overview section.

Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.
PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.
Purpose of This Summary
This PDQ cancer information summary has current information about the treatment of adult laryngeal cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.
Reviewers and Updates
Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Updated") is the date of the most recent change.
The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.
Clinical Trial Information
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Clinical trials can be found online at NCI's website. For more information, call the Cancer Information Service (CIS), NCI's contact center, at 1-800-4-CANCER (1-800-422-6237).
