What is the cause of colon cancer

Oncologists say that the incidence of colon cancer in my country has been gradually increasing. The occurrence of the disease has brought great pain to patients, so it is very important to do a good job in preventing colon cancer. If you want to prevent it, you must know the cause of the disease. So what are the causes of colon cancer? The following oncologists will give you a detailed introduction.

1. 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 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 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 5%.

2. 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 over the age of 10 are likely to develop colon cancer.

3. Chronic colon inflammation: It is also a common cause of colon cancer. It is reported that the prevalence of colon cancer is positively correlated with the prevalence of schistosomiasis. It is generally believed that some of the schistosomiasis will turn into cancer. Other chronic inflammations of the intestine may also turn into 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. Environmental factors: Studies have shown that among various environmental factors, diet is the most important and has a positive correlation with the high fat consumption in food. In addition, the cause of colon cancer is related to the lack of trace elements and changes in lifestyle habits.
