What are the main causes of intestinal cancer?

The occurrence of colorectal cancer mainly occurs in the intestinal area, and tumors will gradually appear in the intestinal area. Therefore, colorectal cancer is also a very serious cancer disease. So, what are the causes of colorectal cancer ? Next, let's learn about it from the following article.

1. Sexual history: Certain colon diseases such as Crohn's disease or ulcerative colitis may increase the chance of developing colon cancer. Their risk of colon cancer is 30 times that of ordinary people. Therefore, this is one of the causes of colon cancer.

2. 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 one of the causes of colorectal cancer.

3. 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 malignancy of about 25%; the malignancy rate of tubular adenomatous polyps is 1-5%.

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.
