Five possible causes of rectal cancer

The latest medical research shows that there are many possible causes of rectal cancer, especially those who have suffered from rectal lesions are more likely to develop rectal cancer, which is very harmful to people's health. So what are the possible causes of rectal cancer ? Let's talk about the possible causes of rectal cancer.

In general, possible causes of rectal cancer include:

1. Malignant transformation of benign tumors: In clinical practice, it is often seen that colorectal adenomas transform into cancer, which shows that the cause of rectal cancer is closely related to colorectal adenomas.

2. Polyps: Most rectal cancers occur on the basis of polyps. In the normal population, the incidence of polyps is 5% to 10%, and in adults over 45 years old, the incidence of polyps is 10%. The incidence of rectal polyps increases with age. This is also one of the causes of rectal cancer.

3. Eating habits: The high incidence areas of rectal cancer are mostly economically developed countries. This has nothing to do with regional differences and racial genetic factors, but is mainly due to differences in eating habits and nutritional methods, such as a diet high in meat, fat, and refined carbohydrates but lacking in refined fiber.

4. Inflammatory stimulation: Chronic ulcerative colitis and other inflammations can cause intestinal mucosal exudation and edema. Repeated destruction and repair processes can cause fibrous tissue hyperplasia, thickening of the intestinal wall, stenosis of the intestinal cavity, epithelial cell metaplasia, and the formation of multiple polyps and chronic granulomas. This is a common cause of rectal cancer.

5. Genetic factors: Familial adenomatous polyposis, hereditary non-polyposis colorectal cancer, etc. are also causes of rectal cancer.

The above is an introduction to the possible causes of rectal cancer, I hope it will be helpful to everyone. Some of these causes of rectal cancer can be prevented in advance, and everyone should actively prevent rectal cancer based on these causes.
