The cause of colon tumor is not very clear, but now some scientific research shows that it is related to the following factors. The first is the dietary factor. Some high-fat and high-calorie diets have a certain relationship with the occurrence of colon cancer. Because a high-fat, high-calorie diet will stimulate the secretion of bile and also cause the growth of intestinal anaerobic bacteria. Anaerobic bacteria secrete some carcinogens from excessive bile, which will stimulate the occurrence of colon cancer. The second aspect is mainly genetic factors. There are 1/4 colon cancer patients with genetic disease history, and his genes determine the high incidence of tumors. The third part, mainly chronic inflammatory stimulation. Some patients with chronic enteritis have a high incidence of tumors. The incidence of general tumor is 8- 10 times higher than that of ordinary patients without colitis, which is supported by a research data. The fourth aspect is mainly intestinal polyp and colon polyp, especially adenomatous polyp, which is a precancerous lesion. Adenomatous polyp occurred for more than 5 years, 10- 15 years. The incidence of colon cancer varies according to its characteristics. Tubular adenoma can reach 5%, villous adenoma is 40%, and the probability of mixed canceration is 22%. In addition to these four factors, long-term mental stress including immune dysfunction, environmental factors and other factors are also risk factors for colon cancer.

There are many factors to prevent colorectal cancer. First, get rid of these bad living habits, keep a happy and open mind, and don't be unhappy, unhappy, which will lead to the occurrence of tumors. Second, pay attention to diet. You can get rid of bad habits for patients, such as eating something indigestible, being too thin and eating less vegetables. These habits are not good, so you should rest assured. In addition, for some pickled products or stale products, traditional kimchi should be eaten as little as possible because it contains some carcinogens after all.
