How is colon cancer caused

Reason 1: long term consumption of high-fat, high protein food. These foods stay in the large intestine for a long time, easy to form carcinogens. Therefore, doctors suggest that we reduce the intake of animal fat, eat more vegetables and fruits, as well as fiber, starch rich food.

Reason two: 25% of the cancers occur in families with a history of intestinal cancer, and most members of some families tend to have polyps. If they are allowed to develop, the incidence rate of colorectal cancer is also 25%. The elderly over 50 years old should take various measures to prevent colorectal cancer.

Reason 3: most colorectal cancers develop from small precancerous lesions, which are called polyps. Villous adenomatous polyps are more likely to develop into cancer, the chance of malignant transformation is about 25%; tubular adenomatous polyps malignant transformation rate is 1-5%.
