If you can get through this article you will see that all cancer is related in some respects to genetics. For that matter so is all life. But when we talk of a genetic link to a particular cancer such as one that would transfer a specific disease from generation to generation oral cancer does not fit the bill. Genetic susceptibility to diseases, or to particular toxins (such as those found in tobacco) is something that we can explore through genetics. Some individuals have a genetic predisposition to certain protections or susceptibilities. But oral cancer is not, except in the most general terms as in all cancers, a genetically caused disease. It is lifestyle related in the largest sense, and viral related in a secondary sense.
