If you want to stay away from rectal cancer, you must start with its cause

At present, the incidence of rectal cancer is getting higher and higher, and the incidence population is also wide. If people do not pay attention to the causes of rectal cancer, the disease may continue to endanger their health. Therefore, we must first understand the causes of rectal cancer in order to better prevent this disease. The following is an introduction to the specific causes of rectal cancer.

Causes of colorectal cancer include:

1. Inflammatory bowel disease: Ulcerative colitis and Crohn's disease are caused by the destruction of intestinal mucosa, the proliferation of ulcer repair, and the formation of granulation tissue, which leads to cancer. Schistosomiasis eggs are deposited in the rectal mucosa, and chronic inflammatory stimulation can lead to the occurrence of rectal cancer. Therefore, this is one of the causes of rectal cancer.

2. Adenoma canceration: Adenomatous polyps can become cancerous, which is considered to be a more important cause of rectal cancer. Adenomas can be divided into three types: tubular adenomas, villous adenomas, and mixed adenomas. Tubular adenomas have a high incidence rate, and villous adenomas have a high rate of canceration. Among adenomas, there are hereditary familial adenomas, which are considered precancerous lesions.

3. Diet: Experts believe that high fat, high protein, and low fiber are related to the occurrence of rectal cancer. The possible reason is that high fat and high protein food can increase the amount of methylcholanthracene in feces, which can increase the secretion of bile acid, and be decomposed into unsaturated polyunsaturated hydrocarbons by anaerobic bacteria in the intestine. Both of these substances are carcinogens; the reduction of fiber slows down the speed of feces passing through the intestine, which increases the contact time between these carcinogens and the intestinal conjunctiva, resulting in an increased chance of cancer. This is also a cause of rectal cancer.

The above mentioned content is the cause of rectal cancer. I hope everyone can understand them one by one. After knowing these causes of rectal cancer, people can better defend against this disease, and then the incidence rate can be greatly reduced. So please be more careful about these causes of rectal cancer, so that you can stay away from the interference of this disease. I wish all patients can fight the disease to the end.
