Experts explain the main causes of colorectal cancer

It is very beneficial for patients with colorectal cancer to understand the causes of colorectal cancer, which helps them receive treatment more scientifically. What are the common causes of colorectal cancer ? The following is a list of common causes of colorectal cancer.

In general, the common causes of colorectal cancer are:

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

2. Genetic factors: There are reports of "familial colorectal cancer" both at home and abroad. The number of blood relatives of colorectal cancer patients who died of the disease is significantly higher than that of the general population. Some colorectal adenomas, such as multiple familial adenomatosis, are autosomal dominant genetic diseases with a family prevalence rate of up to 50%. If not treated, there is a possibility of colorectal cancer after the age of 10. Recently, some scholars have studied the relationship between tumor suppressor genes and colorectal cancer and found that the susceptibility to colorectal cancer and the cause of colorectal cancer are both related to genetic factors.

3. Colon adenoma: According to the research on autopsy materials from various places, the incidence of colon adenoma is quite consistent with that of colon cancer. According to statistics, the incidence of colon cancer in patients with one adenoma is 5 times higher than that of patients without adenoma, and the incidence of patients with multiple adenomas is 1 times higher than that of patients with a single adenoma. This is also a common cause of colon cancer.

4. Chronic colon inflammation: According to reports, the cause of colon cancer is related to 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, such as ulcerative colitis, which has a 3% to 5% chance of cancer.
