Low-fiber diet is closely related to the cause of colorectal cancer

In recent years, with great progress in the diagnosis and treatment of rectal cancer, many people have begun to pay attention to the causes of rectal cancer. Experts say that diet has a direct relationship with the causes of rectal cancer. What are the main causes of rectal cancer? The following is a detailed introduction by experts.

The specific causes of rectal cancer are as follows:

1. Polyps: The etiology of rectal cancer is closely related to polyps. Some people believe that rectal polyps are the precursors of cancer, especially familial multiple adenomatous polyposis, which is very likely to become cancerous; papillary adenomatous polyps also have a higher chance of becoming cancerous.

2. Genetic factors: About 1/4 of the families of patients with rectal cancer have a family history of cancer, and half of them are also digestive tract tumors. Due to the change of genes in normal cells, cancer patients inherit a susceptibility through inheritance, and with certain stimulating factors, tissue cells grow rapidly and develop into cancer. Cell genetic genes mutate and become malignant cells with tumor genetic characteristics, which manifests as familial cancer.

3. Chronic inflammatory stimulation: Chronic inflammatory stimulation can lead to the cause of rectal cancer. For example, schistosomiasis, amoebic dysentery, chronic nonspecific ulcerative colitis, chronic bacillary dysentery, etc. can cause cancer through granuloma, inflammation and pseudopolyp stages. Patients with ulcerative colitis for more than 10 years are prone to evolution, and the degree of cancer is high, easy to metastasize, and the prognosis is poor; according to relevant statistics, the incidence of intestinal cancer patients with colitis is 8 to 10 times higher than that without colitis.

4. Dietary factors: A high-fat, high-meat, low-fiber diet is closely related to the cause of rectal cancer. A high-fat diet can not only stimulate the increase in bile secretion, but also promote the growth of certain anaerobic bacteria in the intestine. Once cholesterol and bile salts are decomposed by anaerobic bacteria to form unsaturated cholesterol, such as deoxycholic acid and lithocholic acid, they increase in the intestine. The latter two are carcinogens or co-carcinogens, and can therefore lead to the occurrence of rectal cancer.
