Oral Cancer
Diagnosis

If an abnormal area has been found in the oral cavity, a biopsy will determine whether it is cancer. Usually, you are referred to a head and neck surgeon, who removes part or all of the lump or abnormal-looking area. A pathologist examines the tissue under a microscope to check for cancer cells.

Almost all oral cancers are squamous cell carcinomas, since squamous cells line the oral cavity.
