Several common causes of rectal cancer

Rectal cancer is one of the common oncological diseases, and many people want to know the cause of rectal cancer , because they hope to do a good job of preventing rectal cancer. So, what is the cause of rectal cancer? Let's take a look at it together!

1. Dietary factors as causes of colorectal cancer

A high-fat, high-meat, low-fiber diet is closely related to the occurrence of rectal cancer. A high-fat diet not only stimulates increased bile secretion, but also promotes the growth of certain anaerobic bacteria in the intestine. Once cholesterol and bile salts are decomposed by anaerobic bacteria to form unsaturated cholesterol, such as deoxycholic acid and lithocholic acid, they increase in the intestine. The latter two are carcinogens or co-carcinogens, and can therefore lead to the occurrence of rectal cancer.

2. Genetic factors

About 1/4 of the families of patients with rectal cancer have a family history of cancer, half of which are also digestive tract tumors. The cause of rectal cancer is due to the change of genes in normal cells. The cancer patient inherits a susceptibility, and with some stimulating factors, the tissue cells grow rapidly and develop into cancer. The cell genetic genes mutate and become malignant cells with tumor genetic characteristics, which manifests as familial cancer.

The above is the introduction to the causes of rectal cancer. It is for your reference only. I hope you can do a good job in preventing rectal cancer and stay away from the causes of rectal cancer.
