Oral cancer can affect all areas, such as the lips, tongue, floor of the mouth and the throat. It can be detected through a thorough and comprehensive oral examination and is found in the form of abnormal oral tissue changes. Common symptoms for oral cancer are an ulcer or sore in the mouth that bleeds easily and does not heal. It may not even be painful. Avoiding risk factors, such as tobacco and alcohol, may decrease your risk of oral cancer. Early detection is key in oral cancer treatment.
