summary

Recently, my aunt always feels a strong tingling in her lower abdomen, and a bit of indigestion. Constipation also occurs. The hospital says that it is colon cancer. Fortunately, in the early stage, let me talk about the causes of colon cancer.

What are the causes of colon cancer

First: chronic colitis: it is reported that the etiology of colon cancer is positively correlated with the endemic areas of schistosomiasis. It is generally believed that the inflammatory changes of the intestinal tract are caused by schistosomiasis, and some of them will be cancerous. The risk of colon cancer in patients with Crohn's disease or ulcerative colitis is 30 times higher than that in normal people.

Second: environmental factors: as proved by research, dietary factors are the most important factors in various environmental factors. The incidence rate of colon cancer is positively related to the high fat consumption in food. In addition, the etiology of colon cancer may be related to the lack of trace elements and the change of living habits.

Third: colon adenoma: autopsy material research found that the incidence of colon adenoma and colon cancer is basically the same, is also a common cause of colon cancer. According to statistics, the incidence of colorectal cancer in patients with single adenoma is 5 times higher than that in patients without adenoma, and that in patients with multiple adenomas is 1 times higher than that in patients with single adenoma. Villous adenomatous polyps are easy to develop into cancer, the malignant transformation rate is about 25%, tubular adenomatous polyps malignant transformation rate is 1-5%.
