"Oral cancer is a serious condition that can develop in any part of the mouth, including the tongue, gums, lips, and throat. In the early stages, oral cancer may not cause any visible symptoms, but may cause pain or difficulty swallowing as it progresses.
Certain lifestyle factors, such as tobacco and alcohol use, can increase the risk of oral cancer. Regular dental check-ups can help detect oral cancer early, when it's most treatable. During a dental exam, your dentist will check your mouth for any signs of abnormal tissue growth or other symptoms of oral cancer."
