Can chronic constipation cause colon cancer?

DIET NOT constipated: Not constipation per se , but diet may a factor: diets high in whole grain, fruits, and veggies have been linked with a lower risk of colorectal cancer, but fiber supplements have not been shown to prevent colo-rectal cancer. Excess red meats and processed meats can increase your colorectal cancer risk and cooking meats at very high heat may create chemicals that might increase cancer risk.

Indirectly: Constipation is typically caused by a diet low in fiber. Eating whole grains, fruits and vegetables regularly (fiber sources) can lower your chances of developing colon cancer.
