Analyze the possible causes of colon cancer for everyone

Colon cancer is a malignant tumor that can cause fatal damage to the digestive system. If the cancer of the colon is not discovered in time, it is likely to cause the colon to completely lose its function and cause fatal damage. 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. 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. This is a common cause of colon cancer. About 1/4 of new patients have a family history of colon cancer. Familial colon polyposis is an autosomal dominant genetic disease with a prevalence of up to 50% in the family. If not treated, people are likely to develop colon cancer after the age of 10.

2. Colon adenoma: Research on autopsy materials found that the incidence of colon adenoma is basically the same as that of colon cancer, and it is also 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 in patients with 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 a malignant transformation rate of tubular adenomatous polyps of 1-5%.

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

4. Chronic colon inflammation: It is reported that the prevalence of intestinal cancer is positively correlated with the prevalence 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. This is a common cause of colon cancer.

The above is an analysis of the common causes of colon cancer. I believe everyone should have some understanding of this. For more questions about the causes of colon cancer, you can consult our online experts, who will answer them in detail and seriously.
