Explain to you the common causes of colorectal cancer

The intestine is a part of the human body that is prone to lesions. The most serious intestinal lesion is of course colon cancer, which may cause the complete loss of intestinal function and cause great harm to patients with colon cancer. What are the common causes of colon cancer ? Let's talk about the common causes of colon cancer.

In general, the common causes of bowel cancer are:

1. History of colorectal polyps: Most colorectal cancers develop from small precancerous lesions, which are called polyps. Among them, villous adenomatous polyps are more likely to develop into colorectal cancer, with a chance of malignant transformation of about 25%; tubular adenomatous polyps have a malignant transformation rate of 1-5%. This is a common cause of colorectal cancer.

2. History of intestinal diseases: This is also a common cause of intestinal cancer. Certain intestinal diseases, such as Crohn's disease or ulcerative colitis, may increase the chance of developing intestinal cancer. Their risk of intestinal cancer is 30 times that of ordinary people.

3. Age: As age increases, the time that various pathogenic factors stimulate the colon mucosa also increases. Most patients with colorectal cancer develop the disease after the age of 50. This is also a common cause of colorectal cancer.

4. Genetic background: Familial adenomatous polyposis and hereditary non-polyposis colorectal cancer are caused by mutations in the corresponding genes. Patients with this type of colorectal cancer not only have a significantly increased risk of developing the disease, but also develop it at a younger age. This is a relatively common cause of colorectal cancer.
