How Is Oral Cancer Diagnosed?
As part of your routine dental exam, your dentist will conduct an oral cancer screening exam. More specifically, your dentist will feel for any lumps or irregular tissue changes in your neck, head, face, and oral cavity. When examining your mouth, your dentist will look for any sores or discolored tissue as well as check for any signs and symptoms mentioned above.

A biopsy may be needed to determine the makeup of a suspicious-looking area. There are different types of biopsies and your doctor can determine which one is best. Many doctors don’t use brush biopsies because while they're very easy, they still need a scalpel biopsy to confirm the results of the brush biopsy are positive. Also, there are different types of scalpel biopsies, incisional and excisional, depending on whether only a piece or the whole area is needed to determine what the nature of the problem is. Some doctors perform these biopsies with lasers.

How Is Oral Cancer Treated?
Oral cancer is treated the same way many other cancers are treated -- with surgery to remove the cancerous growth, followed by radiation therapy and/or chemotherapy (drug treatments) to destroy any remaining cancer cells.
