- Smoking —the most common high-risk behavior
- Excessive use of alcohol
- Race: Black
- Age: 55 or older
- Sex: male
- Occupational exposure to certain air pollutants such as wood dust, chemicals, and asbestos
- Gastroesophageal reflux (GERD) —stomach acid that backs up into the esophagus and throat where it may come in contact with the larynx
- Weakened immune system
- Laryngeal dysplasia—a precancerous condition
- Persistent cough, hoarseness, or sore throat
- Abnormal lump in the throat or neck
- Difficulty swallowing
- Pain when swallowing
- Frequent choking on food
- Difficulty breathing
- Noisy breathing
- Persistent ear pain or an unusual ear fullness or sensation in and around the skin of the ear
- Unplanned, significant weight loss
- Persistent bad breath
- Coughing blood
- Total laryngectomy—This involves the removal of the larynx, including the vocal cords.
- Partial laryngectomy—In this procedure, the surgeon removes the cancerous tissue while leaving as much of the vocal cords as possible.
- Tracheotomy—To help with breathing, a hole is made in the neck below the larynx. This may be temporarily necessary after surgery, or permanently placed in the case of laryngeal tumors that are too large to be removed.
- Neck dissection—This involves the removal of the lymph nodes and part of the neck muscles to determine the spread of cancer.
Radiation Therapy (or Radiotherapy)
- Avoiding excessive alcohol use
- Protecting yourself from toxic exposures that have been linked to laryngeal cancer
