Oral cancer cannot be detected solely by a blood test. If you, your dentist, or your primary care doctor suspects you may have oral cancer, you will likely be referred to an ear, nose and throat specialist. The specialist will perform a complete physical exam and conduct a family history.
A biopsy and blood tests will also be conducted. The blood tests will primarily be ordered just to help determine your overall health before treatment and to be sure there are no other underlying health issues. There are some blood tests that look for cancer markers but these cannot be used to confirm or diagnosis oral cancers.
