Diagnosis

If symptoms or family history raise concerns, the doctor may order a colorectal screening, a fecal occult blood test or other lab work or imaging tests to check for abnormalities.
Stages

A process called staging is used to determine whether colon cancer has spread to other areas in the colon or rectum or to other parts of the body. Stages are ranked 0 to 4, with stage 4 being the most serious. In stage 4, the cancer has been carried through the lymph nodes to other parts of the body and is difficult to treat.
