1. You Have Tongue Cancer
Red or white sores in the mouth and on the tongue that just won’t heal may be symptoms of oral cancer. Oral cancer may occur in the tongue, the floor of the mouth, the tonsils, or the pharynx. The American Cancer Society lists pain, trouble chewing or swallowing, tongue numbness, and trouble moving your tongue among other symptoms of oral cancer. Risk factors for cancers of the mouth include smoking, alcohol use, infection with HPV, and a poor diet. A diagnosis of stage I or II cancer of the tongue may require surgery or radiation.
