DiagnosisDifferent tests are used to diagnose and show the extent of the cancer within the body (stage). Tests can also show if the tumor is likely to grow and spread (grade). Doctors use the cancer stage and tumor grade information, together with other factors, to plan the best treatment, make a prognosis, and identify clinical trials. Learn about different tests, reports, and how to find a doctor or medical center.
