Diagnosis of tongue cancer begins with a thorough medical history review and physical exam. Your doctor may remove a small tissue sample (biopsy) of the potential cancer to send to the laboratory for analysis. Mayo Clinic pathologists experienced in identifying oral cancers will examine the tissue under a microscope to determine if cancer cells are present.
Your treatment team also may order one or more imaging tests (X-rays, CT scan, MRI scan or PET scan) to determine how far the tongue cancer has spread. Tests are scheduled quickly, in a coordinated manner, and results are often back the same day.
