Analyze the four major causes of colon cancer for everyone

According to the latest statistics from authoritative organizations, 8 million people worldwide face the threat of colon cancer every year, which means that 10-20 out of 100 malignant tumor patients are colon cancer patients, and the incidence rate is relatively high. What are the common causes of colon cancer ? The following will introduce 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 incidence of colon cancer is positively correlated with the high fat consumption in food. In addition, the cause of colon cancer may be related to the lack of trace elements and changes in lifestyle habits.

2. Colon adenoma: Studies on autopsy materials have 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 colorectal 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 a malignant transformation rate of tubular adenomatous polyps of 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. It is also 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 rate of up to 50% in the family. If not treated, people are likely to develop colon cancer after the age of 10.
