Oral cancer is a growth or a sore in the mouth that exists for very long period of time or does not go away at all. This can form in any part of the mouth.Lips, tongue, cheeks, floor of the mouth, hard and soft palate, sinuses, and pharynx (throat) are the parts in which it usually occurs and it can be a life threatening if not diagnosed and treated early. Most oral cancers begin in the flat cells that cover the surfaces of your mouth, tongue, and lips. Anyone can get oral cancer, but the risk is higher if you are male, use tobacco, drink lots of alcohol, have HPV, or have a history of head or neck cancer. Frequent sun exposure is also a risk factor for lip cancer. The symptoms of oral cancer includes: white or red patches in your mouth, a mouth sore that won't heal, bleeding in your mouth, loose teeth, problems or pain with swallowing, a lump in your neck, an earache. It can be diagnosed by a physical exam, endoscopy, biopsy, and imaging tests. Oral cancer treatments may include surgery, radiation therapy, and chemotherapy. Some patients have a combination of treatments.
