Mayo Clinic doctors use highly advanced diagnostic services to identify floor of the mouth cancer. The process starts with a physical exam and a discussion of your symptoms and medical history.
Your doctor may take a small sample of tissue (biopsy) to send to the lab for analysis. X-rays help locate abnormalities in the floor of your mouth and jaws. Your doctor may order other imaging tests, such as those below, to determine if the cancer has spread. In tests that involve radiation, Mayo Clinic specialists carefully monitor doses to avoid the risk of radiation overexposure.
