Information for Patients


Oral Cancer

Oral cancer can form in any part of the mouth. Most oral cancers begin in the flat cells that cover the surfaces of your mouth, tongue, and lips. Anyone can get oral cancer, but the risk is higher if you are male, use tobacco, drink lots of alcohol, have HPV, or have a history of head or neck cancer. Frequent sun exposure is also a risk factor for lip cancer.

Symptoms of oral cancer include

  • White or red patches in your mouth
  • A mouth sore that won't heal
  • Bleeding in your mouth
  • Loose teeth
  • Problems or pain with swallowing
  • A lump in your neck
  • An earache

Tests to diagnose oral cancer include a physical exam, endoscopy, biopsy, and imaging tests. Oral cancer treatments may include surgery, radiation therapy, and chemotherapy. Some patients have a combination of treatments.

Throat Cancer

Also called: Hypopharyngeal cancer, Laryngeal cancer, Laryngopharyngeal cancer, Nasopharyngeal cancer, Oropharyngeal cancer, Pharyngeal cancer

Throat cancer is a type of head and neck cancer. Throat cancer has different names, depending on which part of the throat is affected. The different parts of your throat are called the oropharynx, the hypopharynx, the nasopharynx, and the larynx, or voice box.

The main risk factors for throat cancer are using tobacco heavy drinking. Certain types of throat cancer also have other risk factors. For example, having HPV is a risk factor for oropharyngeal cancer.

Symptoms of throat cancer may include

  • A sore throat that does not go away
  • A lump in the neck
  • Pain or ringing in the ears
  • Trouble swallowing
  • Ear pain

To diagnose throat cancers, doctors may do a physical exam and history, imaging tests, and a biopsy. You may also need other tests, depending on the type of cancer. Treatments include surgery, radiation therapy, and chemotherapy. Treatment for some types of throat cancer may also include targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.
