Laryngeal cancer
Laryngeal Cancer
Laryngeal cancer (pronunciation: luh-RIN-jee-ul KAN-ser) is a type of cancer that starts in the larynx, also known as the voice box.
Etymology
The term "laryngeal" is derived from the Greek word "larynx," which means "throat," and "cancer" is derived from the Latin word "cancer," which means "crab" or "creeping ulcer."
Definition
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, allowing us to speak.
Types
There are several types of laryngeal cancer, which are classified based on the area of the larynx where they start. These include:
- Glottic cancer: This starts in the vocal cords.
- Supraglottic cancer: This starts in the upper part of the larynx and includes cancer that affects the epiglottis, which helps direct food to the esophagus and air to the windpipe.
- Subglottic cancer: This starts in the lower part of the voice box, below the vocal cords.
Symptoms
Common symptoms of laryngeal cancer include a sore throat or cough that does not go away, trouble swallowing, ear pain, trouble breathing, weight loss, and a lump or mass in the neck.
Causes and Risk Factors
The exact cause of laryngeal cancer is not known, but certain risk factors have been identified, including tobacco use, heavy alcohol use, exposure to certain chemicals and substances, and a family history of head and neck cancer.
Treatment
Treatment for laryngeal cancer may include surgery, radiation therapy, chemotherapy, or a combination of these. The choice of treatment depends largely on the stage of the cancer and the patient's overall health.
