About Oropharyngeal Cancer
Among the top in cancer research and care. The only National Cancer Institute-designated Comprehensive Cancer Center in the Mountain West.
Oropharyngeal cancer is a disease in which cancer cells form in the tissues of the oropharynx. The oropharynx includes the soft palate, side and back walls of the throat, tonsils, and back one-third of the tongue.
Signs & Symptoms
These are signs and symptoms of oropharyngeal cancer:
- A sore throat that does not go away
- Trouble swallowing
- Trouble opening the mouth fully
- Trouble moving the tongue
- Weight loss for no clear reason
- Ear pain
- A lump in the back of the mouth, throat, or neck
- A white patch on the tongue or lining of the mouth that does not go away
- Coughing up blood
Other health problems can also cause these signs. If you have any of these signs, see your doctor as soon as possible.

Causes & Risk Factors
A risk factor is anything that raises your chance of getting a disease. Having a risk factor does not mean you are sure to get cancer. It means your chances are higher than the average person’s. Talk with your doctor to learn more about your cancer risk.
These are risk factors for getting oropharyngeal cancer:
- Having the human papillomavirus (HPV)
- A personal history of other types of head and neck cancer
- Heavy alcohol use
Diagnosis & Stages
Diagnosis of Oropharyngeal Cancer
These tests are used to diagnose oropharyngeal cancer:
- Physical exam and history: A health care provider looks at your body for signs of disease. Your symptoms, personal health habits, and past illnesses help guide the exam.
- Imaging tests: A health care provider uses dyes, x-rays, magnets, radio waves, or computer technology to make detailed pictures of internal organs. The provider may inject dye or have you swallow dye to help see the images.
- Biopsy: The health care provider removes cells or tissues with a small scope. Then a doctor looks at the cells or tissues under a microscope to check for signs of cancer.
Stages of Oropharyngeal Cancer
Staging is the process that shows whether cancer has spread to other parts of the body. Cancer spreads in the body in three ways: through tissue, the lymph system, or the blood.
These are the stages used for oropharyngeal cancer:
- Stage 0 (carcinoma in situ): Abnormal cells are found in the lining of the oropharynx.
- Stage I: Cancer has formed in the oropharynx only and is 2 centimeters or smaller.
- Stage II: Cancer has formed in one the oropharynx only and is 2–4 centimeters.
- Stage III: Cancer has spread to one lymph node or has spread to the epiglottis (the flap that covers the trachea during swallowing).
- Stage IV (IVA, IVB, and IVC): Cancer has spread to other parts of the body or more lymph nodes.
When cancer spreads from where it started to another part of the body, it is called metastasis. These metastatic cancer cells are the same type of cancer as the primary tumor. For example, if oropharyngeal cancer spreads to the bone, the cancer cells in the bone are actually oropharyngeal cancer cells. The disease is metastatic oropharyngeal cancer, not bone cancer.
