What are the main causes of rectal cancer?

Rectal cancer is a type of cancer, and most people don't know much about it. In fact, if you want to cure rectal cancer, it is very important to find the cause of rectal cancer . Next, let's learn more about this.

1. Eating habits: The high incidence of colorectal cancer is mostly in economically developed countries. This has nothing to do with regional differences and racial genetic factors. It is mainly due to differences in eating habits and nutritional methods. For example, the diet contains a lot of meat, fat, and refined carbohydrates, but lacks refined fiber. Therefore, this is one of the causes of colorectal cancer.

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

3. Inflammatory stimulation: This is also a common factor that leads to rectal cancer. Since 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, formation of multiple polyps and chronic granulomas, thus causing the occurrence of rectal cancer.

4. Genetic factors such as familial adenomatous polyposis, hereditary non-polyposis colorectal cancer, etc.
