Experts explain possible causes of colon cancer

Colon cancer is a tumor disease that causes fatal damage to intestinal health. Many patients with colon cancer will gradually lose the functions of their intestines, which has a huge impact on their health. What are the common causes of colon cancer ? Let's talk about the common causes of colon cancer.

Common causes of colon cancer include:

1. Environmental factors: Studies have shown that among various environmental factors, diet is the most important, and the cause of colon cancer is positively correlated with high fat consumption in food. In addition, it may also be related to the lack of trace elements and changes in lifestyle habits.

2. Colon adenoma: Research on autopsy materials has found that the incidence of colon adenoma is basically the same as that of colon cancer, and it is a common cause of colon cancer. According to statistics, the incidence of colon cancer in patients with a single adenoma is 5 times higher than that in patients without adenoma, and the incidence of multiple adenomas is 1 times higher than that in patients with a single adenoma. Villous adenomatous polyps are prone to develop into cancer, with a malignant transformation rate of about 25%, and the malignant transformation rate of tubular adenomatous polyps is 1-5%.

3. Chronic colon inflammation: According to reports, the cause of colon cancer is positively correlated with the endemic area of ​​schistosomiasis. It is generally believed that due to schistosomiasis, inflammatory changes in the intestines may lead to cancer in some parts. Other chronic inflammations of the intestines may also lead to cancer. For example, the risk of colon cancer in patients with Crohn's disease or ulcerative colitis is 30 times that of ordinary people.

4. Genetic factors: If a person's first-degree relatives, such as parents, have had colon cancer, the risk of this disease is 8 times higher than that of ordinary people. About 1/4 of new patients have a family history of colon cancer. Familial colon polyposis is an autosomal dominant genetic disease with a family prevalence of up to 50%. If not treated, people are likely to develop colon cancer after the age of 10. This is a common cause of colon cancer.
