Throat cancer (larynx cancer) facts*
*Throat cancer (larynx cancer) facts
What is cancer?
Cancer begins in cells, the building blocks that make up tissues. Tissues make up the larynx and the other organs of the body.
Normal cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells take their place.
Sometimes, this process goes wrong. New cells form when the body doesn't need them, and old or damaged cells don't die as they should. The buildup of extra cells often forms a mass of tissue called a growth or tumor. The types of cells which form the tumor determine how the tumor will behave.
Tumors in the larynx can be benign (not cancer) or malignant (cancer). Benign tumors are not as harmful as malignant tumors:
Laryngeal cancer cells can spread by breaking away from the tumor in the larynx. The process of spread is called metastasis. The cancer cells can travel through lymph vessels to nearby lymph nodes. They can also spread through blood vessels to the lungs, bones, or liver. After spreading, laryngeal cancer cells may attach to other tissues and grow to form new tumors that may damage those tissues.
Who is at risk for larynx cancer?
When you get a diagnosis of laryngeal cancer, it's natural to wonder what may have caused the disease. Doctors can't always explain why one person gets laryngeal cancer and another doesn't.
However, we do know that people with certain risk factors may be more likely than others to develop laryngeal cancer. A risk factor is something that may increase the chance of getting a disease.
Smoking tobacco causes most laryngeal cancers. Heavy smokers who have smoked tobacco for a long time are most at risk for laryngeal cancer.
Also, people who are heavy drinkers are more likely to develop laryngeal cancer than people who don't drink alcohol. The risk increases with the amount of alcohol that a person drinks. The risk of laryngeal cancer increases even more for people who are heavy drinkers and heavy smokers. However, not everyone who drinks or smokes heavily will develop the disease.
Many other possible risk factors are under study. For example, researchers are studying whether an HPV infection in the throat may increase the risk of laryngeal cancer. HPV is a group of viruses that can infect the body. HPV causes the vast majority of cervix cancer and at least half of the oropharynx cancers today. Another area of research is whether reflux (the backward flow of liquid from the stomach to the throat) may increase the risk of laryngeal cancer.
How to Quit TobaccoQuitting is important for anyone who uses tobacco. Quitting at any time is beneficial to your health.
For people who already have laryngeal cancer, quitting may reduce the chance of cancer returning after treatment. Quitting may also reduce the chance of getting another type of cancer (such as lung, esophagus, or oral cancer), lung disease, or heart disease caused by tobacco. In addition, quitting can help cancer treatments work better.
There are many ways to get help:
What are symptoms of larynx cancer?
The symptoms of laryngeal cancer depend mainly on the size and location of the tumor. Common symptoms of laryngeal cancer include:
Other symptoms may include:
These symptoms may be caused by laryngeal cancer or by other health problems. People with these symptoms should tell their doctor so that any problem can be diagnosed and treated as early as possible.
How is larynx cancer diagnosed?
If you have symptoms that suggest laryngeal cancer, your doctor may do a physical exam. Your doctor looks at your throat and feels your neck for lumps, swelling, or other problems.
You may have one or more of the following tests:
If you need a biopsy, you may want to ask your doctor some of the following questions:
How is staging for throat cancer determined?
If laryngeal cancer is diagnosed, your doctor needs to learn the extent (stage) of the disease to help you choose the best treatment. When laryngeal cancer spreads, cancer cells may be found in the lymph nodes in the neck or in other tissues of the neck. Cancer cells can also spread to the lungs, liver, bones, and other parts of the body.
To learn whether laryngeal cancer has invaded nearby tissues or spread, your doctor may order one or more tests:
When cancer spreads from its original place to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary (original) tumor. For example, if laryngeal cancer spreads to a lung, the cancer cells in the lung are actually laryngeal cancer cells. The disease is metastatic laryngeal cancer, not lung cancer. It's treated as laryngeal cancer, not as lung cancer. Doctors sometimes call the new tumor "distant" disease.
Doctors describe the stage of laryngeal cancer based on the size of the tumor, whether the vocal cords move normally, whether the cancer has invaded nearby tissues, and whether the cancer has spread to other parts of the body:
What are treatment options for larynx cancer?
People with early laryngeal cancer may be treated with surgery or radiation therapy. People with advanced laryngeal cancer may have a combination of treatments. For example, radiation therapy and chemotherapy are often given at the same time. Targeted therapy is another option for some people with advanced laryngeal cancer.
The choice of treatment depends mainly on your general health, where in your larynx the cancer began, and whether the cancer has spread.
You may have a team of specialists to help plan your treatment. Your doctor may refer you to a specialist, or you may ask for a referral. Specialists who treat laryngeal cancer include:
Other health care professionals who work with the specialists as a team may include a dentist, plastic surgeon, reconstructive surgeon, speech-language pathologist, oncology nurse, registered dietitian, and mental health counselor.
Your health care team can describe your treatment choices, the expected results of each, and the possible side effects. You'll want to consider how treatment may affect eating, swallowing, and talking, and whether treatment will change the way you look during and after treatment. You and your health care team can work together to develop a treatment plan that meets your needs.
Before, during, and after cancer treatment, you can have supportive care to control pain and other symptoms, to relieve the side effects of treatment, and to ease emotional concerns. Information about supportive care is available on NCI's Web site at http://www.cancer.gov/cancertopics/coping.
Also, NCI's Cancer Information Service can answer your questions about supportive care. Call 1–800–4–CANCER (1–800–422–6237). Or chat using LiveHelp, NCI's instant messaging service, at http://www.cancer.gov/livehelp.
You may want to talk with your doctor about taking part in a clinical trial. Clinical trials are research studies testing new treatments. They are an important option for people with all stages of laryngeal cancer.
You may want to ask your doctor these questions before you begin treatment:
Surgery
Surgery is a common treatment for people with cancer of the larynx. The surgeon may use a scalpel or laser. Laser surgery may be performed with a laryngoscope. You and your surgeon can talk about the types of surgery and which may be right for you:
It takes time to heal after surgery, and the time needed to recover is different for each person. It's common to feel weak or tired for a while, and your neck may be swollen.
Also, you may have pain or discomfort for the first few days. Medicine can help control your pain. Before surgery, you should discuss the plan for pain relief with your doctor or nurse. After surgery, your doctor can adjust the plan if you need more pain control.
Surgery may change your ability to swallow, eat, or talk. You may need to have reconstructive or plastic surgery to rebuild the tissue. The surgeon may use tissue from another part of your body to repair the throat. You can have reconstructive or plastic surgery at the same time as you have the cancer removed, or you can have it later on. Talk with your doctor about which approach is right for you.
If you lose the ability to talk for a short time after surgery, you may find it helpful to use a notepad, writing toy (such as a magic slate), cell phone, or computer to write messages. Before surgery, you may want to make a recording for your answering machine or voicemail that tells callers that you have lost your voice.
Some people may need a temporary feeding tube.
StomaThe surgeon may need to make a stoma. The stoma is a new airway through an opening in the front of your neck.
Air enters and leaves the trachea and lungs through this opening. A metal or plastic tube (a "trach," or tracheostomy tube) keeps the new airway open.
Before you leave the hospital, your health care team will teach you how to care for the stoma. You will learn to remove and clean the trach tube, clean out your airway, and care for the skin around the stoma.
You may want to follow these tips:
For many people, the stoma is needed only until recovery from surgery. Several days after surgery, the tube will be removed, and the stoma will close up. If your entire larynx is removed, the stoma will be permanent. You will then need to learn to use a special device to enable you to speak as you no longer have vocal cords.
People with stomas work in almost every type of business and can do nearly all of the things they did before surgery. However, they can't hold their breath, so heavy lifting may be hard. Also, swimming and water skiing are not possible without a special device and training to keep water out of the lungs.
Some people may feel self-conscious about the way they look and speak with a stoma. They may be concerned about how other people feel about them. They may also be concerned about how their sex life may be affected. Many people find that talking about these concerns is helpful.
You may want to ask your doctor these questions before having surgery:
Radiation Therapy
Radiation therapy uses high-energy rays to kill cancer cells. It's an option for people with any stage of laryngeal cancer. People with small tumors may choose radiation therapy instead of surgery. It may also be used after surgery to destroy cancer cells that may remain in the area.
The radiation comes from a large machine outside the body. You may go to the hospital or clinic once or twice a day, generally 5 days a week for several weeks. Each treatment takes only a few minutes.
Radiation therapy aimed at the neck may cause side effects:
Some side effects go away after radiation therapy ends, but others last a long time. Although the side effects of radiation therapy can be upsetting, your doctor can usually treat or control them. It helps to report any problems that you are having so that your doctor can work with you to relieve them.
You may want to ask your doctor these questions before having radiation therapy:
Chemotherapy
Chemotherapy uses drugs to kill cancer cells. The drugs that treat laryngeal cancer are usually given through a vein (intravenous). The drugs enter the bloodstream and travel throughout your body.
Chemotherapy and radiation therapy are often given at the same time. You may receive chemotherapy in an outpatient part of the hospital, at the doctor's office, or at home. Some people need to stay in the hospital during treatment.
The side effects depend mainly on which drugs are given and how much. Chemotherapy kills fast-growing cancer cells, but the drugs can also harm normal cells that divide rapidly:
Also, chemotherapy can cause painful mouth and gums, dry mouth, infection, and changes in taste. Some drugs used for laryngeal cancer can cause tingling or numbness in the hands or feet. You may have these problems only during treatment or for a short time after treatment ends.
Targeted Therapy
Some people with laryngeal cancer receive a type of treatment known as targeted therapy. It may be given along with radiation therapy.
Cetuximab (Erbitux) was the first targeted therapy approved for laryngeal cancer. Cetuximab binds to cancer cells and interferes with cancer cell growth and the spread of cancer. You may receive cetuximab through a vein once a week for several weeks at the doctor's office, hospital, or clinic.
During treatment, your health care team will watch for signs of problems. Some people get medicine to prevent a possible allergic reaction. Side effects may include rash, fever, headache, vomiting, and diarrhea. These effects usually become milder after the first treatment.
You may want to ask your doctor these questions about chemotherapy or targeted therapy:
How does a person get a second opinion after a throat cancer diagnosis
Before starting treatment, you may want a second opinion about your diagnosis, stage of cancer, and treatment plan. Some people worry that the doctor will be offended if they ask for a second opinion. Usually the opposite is true. Most doctors welcome a second opinion. And many health insurance companies will pay for a second opinion if you or your doctor requests it. Some companies require a second opinion.
If you get a second opinion, the second doctor may agree with your first doctor's diagnosis and treatment plan. However, if the second opinion doctor has a different opinon, he or she may suggest another approach, and may help you decide between them. Either way, you'll have more information and perhaps a greater sense of control. You can feel more confident about the decisions you make, knowing that you've looked at all of your options.
It may take some time and effort to gather your medical records and see another doctor. The delay in starting treatment usually will not make treatment less effective. To make sure, you should discuss this delay with your doctor.
There are many ways to find a doctor for a second opinion. You can ask your doctor, a local or state medical society, a nearby hospital, or a medical school for names of specialists.
Also, you can get information about treatment centers near you from NCI's Cancer Information Service. Call 1–800–4–CANCER (1–800–422–6237). Or chat using LiveHelp, NCI's instant messaging service, at http://www.cancer.gov/ livehelp.
