The occurrence of rectal cancer has a lot to do with our diet

The causes of rectal cancer are quite complicated. Many factors may cause the occurrence of rectal cancer, especially our eating habits are closely related to the occurrence of rectal cancer. So, what are the main causes of common rectal cancer? Let's ask the experts to tell us in detail about the causes of rectal cancer .

The main causes of rectal cancer are:

The incidence of rectal cancer is closely related to polyps, which are the direct cause of rectal cancer. Most rectal cancers occur on the basis of polyps. In the normal population, the incidence of polyps is only 5% to 10%. In adults over 45 years old, the incidence of polyps is 10%. Elderly people over 50 years old should take various measures to prevent rectal cancer. Because 50% of elderly people over 60 years old will develop large intestinal polyps. But we don't know which of these polyps of different sizes will develop into rectal cancer. The incidence of rectal polyps increases with age. Malignant transformation of benign tumors: In clinical practice, it is often seen that colorectal adenomas become cancerous, indicating that the cause of rectal cancer is closely related to colorectal adenomas. 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 relatively high chance of becoming cancerous.

Secondly, long-term consumption of high-fat, high-protein foods is also a cause of colorectal cancer. These foods stay in the large intestine for a long time and are prone to form carcinogens. A high-fat, high-meat, low-fiber diet is closely related to the occurrence of colorectal 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, there is an increase in the intestine. The latter two are both carcinogens and co-carcinogens, so they can lead to the occurrence of colorectal cancer.

About 1/4 of the families of patients with rectal cancer have a family history of cancer, half of which are digestive tract tumors. Due to the change of genes in normal cells, cancer patients inherit a susceptibility, 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.

In addition, the occurrence of tumors is closely related to mental factors, age, endocrine factors, environmental stress, climate factors, immune dysfunction and viral infection. Therefore, the causes of rectal cancer are diverse, so people should pay attention to their health problems in all aspects of life, eat less high-fat and high-protein foods, and pay attention to changes in their bodies. As long as you find something wrong with your body, you should seek medical attention in time.
