Dr. Manish Sharma is one of the best oral cancer specialist in Delhi. High-risk factors for oral cancer include smoking cigarettes, cigars, or pipes; chewing tobacco or using snuff; drinking excessive alcohol; having unprotected sun exposure to the lips; and chewing betel nut. The risk is even higher when people have more than one of these unhealthy habits. However, it can also occur on the floor of the mouth, cheek lining, gingiva (gums), lips, or palate (roof of the mouth). Most oral cancers look very similar to each other under a microscope and are classified as squamous cell carcinoma.
