About Oral Cancer
Lip and oral cavity cancer (also called oral cancer) is a disease where cancerous cells form in the lips or mouth. Huntsman Cancer Institute experts recommend having your dentist screen for oral cancer at routine check-ups. If you notice any of the signs and symptoms of oral cancer between check-ups, make an appointment with your doctor or an ear, nose, and throat specialist.
Signs & Symptoms
These are signs of lip and oral cavity cancer:
- A sore on the lip or in the mouth that does not heal
- A lump or thickening on the lips or gums or in the mouth
- A white or red patch on the gums, tongue, or lining of the mouth
- Bleeding, pain, or numbness in the lip or mouth
- Loose teeth or dentures that no longer fit well
- Difficulty chewing or swallowing or moving the tongue or jaw
- Swelling of the jaw
- Sore throat or feeling that something is caught in the throat
- Change in voice
Many 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
Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean you are sure to get cancer. It means your chances are higher than the average person鈥檚. Talk with your doctor to learn more about your cancer risk.
The chance of getting lip or oral cavity cancer increases with tobacco use. These are other risk factors:
- Excess exposure to natural or artificial sunlight
- Having the human papillomavirus (HPV)
- Drinking alcohol

Diagnosis & Stages
Diagnosis of Oral Cancer
Doctors use these tests to diagnose lip and oral cavity cancer:
- Physical exam and history: A health care provider examines your oral cavity for signs of disease. Your personal health habits, past illnesses, and symptoms help guide the exam.
- Imaging tests: Using dyes, x-rays, magnets, radio waves, and/or computer technology, your health care provider can create detailed images of internal organs. Your health care provider may inject or have you swallow a dye to help see the images.
- Exfoliative cytology: Your health care provider removes cells or tissues with a swab, in the lip or oral cavity, so they can be viewed under a microscope to check for signs of cancer.
- Biopsy: The health care provider removes cell or tissue samples so they can be viewed under a microscope to check for signs of cancer.
Stages of Oral Cancer
Cancer stages show whether cancer has spread within or around the lips and mouth or 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 lip and oral cavity cancer:
- Stage 0 (carcinoma in situ): Abnormal cells are in the lining of the lips and oral cavity.
- Stage 1: Cancer has formed, and the tumor is less than 2 centimeters.
- Stage 2: The tumor is larger than 2 centimeters, but less than 4.
- Stage 3: The tumor may be any size and has spread to the lymph nodes, or it is larger than 4 centimeters.
- Stage 4 (4A, 4B, & 4C): The tumor has spread outside the lip or oral cavity and may have spread to other parts of the body.
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 lip or oral cancer spreads to the bone, the cancer cells in the bone are actually lip or oral cancer cells. The disease is metastatic lip or oral cancer, not bone cancer.
