What causes stage 4 rectal cancer?

Dr. Jeanne Morrison, PhD
Family Practitioner

Growths called polyps and nonpolypoid lesions can grow on the inner lining of the rectum and lead to rectal cancer. The exact cause of these growths is not known, but they can be detected and removed during a routine exam before cancer develops. Genetics can also make you more prone to developing rectal cancer. Some environmental factors, such as a diet high in fat and low in fiber, can also trigger rectal cancer. Stage 4 rectal cancer develops when the cancer is not treated at an earlier stage.
