What causes rectal cancer

summary

Patients with colon and rectal cancer often have recurrent diarrhea, which is not easy to cure, and the digestive ability is weakened, so we must pay attention to eating some easy to digest food in the diet.

What causes rectal cancer

One reason: dietary factors, such as high-fat meat food, high protein food and low fiber diet, such as starch, potatoes, carrots and so on, have a very important relationship with the pathogenesis of rectal cancer. High fat diet can not only stimulate the increase of bile secretion, but also promote the synthesis of cholesterol and cholic acid in the liver, so it increases in the intestinal cavity and changes under the action of colonic bacteria Low fiber food does not absorb water, reduces the frequency of defecation, increases the residence time of waste in the intestinal tract, prolongs the residence time of feces in the large intestine, and increases the long-term contact between carcinogens and large intestine mucosa, thus becoming one of the causes of colorectal cancer.

The second reason: genetic factors, genetic factors is one of the causes of rectal cancer, in the family of rectal cancer patients, about 1 / 4 of the new patients have a family history of rectal cancer, relatives have had rectal cancer, their offspring suffer from this disease more than the general population in their lifetime, cell genetic gene changes, resulting in malignant cells of tumor genetic characteristics, forming a family of malignant tumors Nationality.

Reason 3: rectal polyps, rectal polyps is one of the main factors of rectal cancer. Poor rectal polyps are the main cause of precancerous lesions, especially familial multiple adenomatous polyposis. The canceration rate of papillary adenomatous polyps was about 25%, and tubular adenomatous polyps were not uncommon.
