(Cancer of the Larynx; Cancer of the Voicebox )
by Rick Alan
Laryngeal cancer is a disease in which cancer cells grow in the larynx. The larynx is a tube-shaped organ inside the neck that lies between the throat and the windpipe. Its main function is to produce sound for speaking.
Cancer occurs when cells in the body—in this case laryngeal cells—divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant tumors, which can invade nearby tissues and can spread to other parts of the body. A benign tumor does not invade or spread.
The cause of laryngeal cancer is not known.
Risk Factors TOP
Factors that increase your chance of getting laryngeal cancer include:
Symptoms may include:
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Your bodily tissue may need to be tested. This can be done with biopsy.
Your internal structures may need to be viewed and examined. This can be done with:
When laryngeal cancer is found, staging tests are performed to find out if the cancer has spread and, if so, to what extent. Treatment depends on the stage of the cancer. For early stage laryngeal cancer, either surgery or radiation alone are the most common and appropriate therapies offered. For more advanced disease, either radiation with chemotherapy or surgery followed by radiation is the most common treatment given.
Surgery requires removal of a cancerous tumor and nearby tissue, and possibly nearby lymph nodes. Surgeries for laryngeal cancer include:
Radiation Therapy (or Radiotherapy)
Radiation therapy is the use of radiation to kill cancer cells and shrink tumors. This may be external radiation therapy, where the beam is directed at the tumor from a source outside the body.
Chemotherapy is the use of drugs to kill cancer cells. This form of treatment may be given in many forms including pill, injection, and catheter. The drugs enter the bloodstream and travel through the body killing mostly cancer cells, but also some healthy cells. Chemotherapy may be used to reduce the size of a particularly large cancer.
Since laryngeal cancer is extremely rare in nonsmokers, the best way to prevent this type of cancer is by not smoking. Other measures you can take to reduce your risk of laryngeal cancer include:
