What causes colon cancer

There are many causes of colon cancer, such as genetic factors, dietary factors, chronic inflammation, precancerous lesions, etc.

1. Genetic factors: Colorectal cancer is somewhat hereditary. If a family member has colorectal cancer, the patient’s children will have an increased chance of developing colorectal cancer.

2. Dietary factors: If you eat a high-protein diet for a long time and consume relatively less fresh vegetables and foods rich in dietary fiber, the incidence of colon cancer will increase.

3. Chronic inflammation: If you suffer from diseases such as ulcerative colitis and Crohn's disease, your intestines will suffer from chronic inflammation, the intestinal mucosa will be repeatedly destroyed and repaired, and the intestinal mucosal epithelial cells will proliferate, which may increase the risk of cancer.

4. Precancerous lesions: mainly refer to intestinal polyps. Intestinal polyps are benign diseases, but as time goes by, polyps may become cancerous, especially adenomatous polyps, which have a relatively high risk of cancer.

After colorectal cancer occurs, a comprehensive examination is needed, including CT, colonoscopy, etc., to determine the severity of the disease and then decide how to treat it.
