Although they comprise fewer than 1% of all gastrointestinal (GI) tumors, gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the GI tract.

Risk factors (things that increase your risk) for oral cancer include smoking (or using smokeless tobacco) and heavy alcohol use. Other risk factors are being male, using marijuana, or having human papillomavirus (HPV).

A lump or thickening on your lips, gums, cheek, or in your mouth
A white or red patch on your gums, your tongue, tonsils, or
the lining of your mouth
A sore throat or a feeling that something
is caught in your throat
Unexplained difficulty chewing,
swallowing, speaking, or moving your jaw or tongue
Numbness or pain in your tongue or
other areas of your lips or mouth
Swelling in your jaw that makes your
teeth loose or your dentures fit poorly
Changes in your voice
Dry mouth (xerostomia)
Your dentist or doctor may look closely at your lips, mouth, or throat to check for signs of oral cancer. Other tests may be needed if there are possible signs of cancer, such as a biopsy, an X-ray, or an MRI.
Oral cancer is usually treated with surgery and radiation therapy. Your treatment will depend on the stage of your cancer and your other health factors. If the cancer is advanced, other treatments may be used. You may get chemotherapy. Or chemotherapy and targeted therapy may be used together.
