Oral Precancer and Cancer

Oral cancer is a well known disorder causing mortality. Even though many etiological factors have been proposed, but it is mainly due to tobacco (smoking and smokeless form). This tobacco has several carcinogenic substances which results in the formation of cancer. We represent a male patient 60 years of age with Oral cancer in the left vestibule induced due to smokeless tobacco. It was associated with leukoplakia in the left buccal mucosa.
