Common causes of rectal cancer

I believe that many people are concerned about the causes of rectal cancer. Rectal cancer is a common malignant tumor that has a great impact on people's physical and mental health and cannot be ignored. So what are the common causes of rectal cancer ? The following is a detailed answer from relevant experts.

Experts say that the main causes of rectal cancer are as follows. Let’s take a look:

(1) Dietary factors. Dietary factors are one of the causes of colorectal cancer. Experts point out that the so-called Western diet, which is high in fat, protein, and low in fiber, is believed to be related to the occurrence of colorectal cancer. This is because high-fat and high-protein foods can increase the amount of methylcholanthracene in feces, which can increase the secretion of bile acid and be decomposed into unsaturated polyunsaturated hydrocarbons by anaerobic bacteria in the intestines. Both of these substances are carcinogens. How does colorectal cancer occur? A decrease in the amount of fiber in food can also increase the chance of cancer.

(2) Genetic factors. The occurrence of rectal cancer may be related to genetic factors. Experts say that in the families of rectal cancer patients, there are many with a family history of cancer and many digestive tract tumors. Due to the change of genes in normal cells, cancer patients inherit a susceptibility, and with some stimulating factors, tissue cells grow rapidly, which will develop into cancer. This is also one of the common causes of rectal cancer.

(3) Inflammatory bowel disease. How does rectal cancer develop? The development of rectal cancer is also related to inflammatory bowel disease. Ulcerative colitis and Crohn's disease, for example, are caused by the destruction of the intestinal mucosa, the proliferation of ulcer repair, and the formation of granulation tissue, which can lead to cancer. For example, the deposition of schistosomiasis eggs in the rectal mucosa and chronic inflammatory stimulation can lead to cancer.

(4) Adenoma canceration. Experts say that adenoma canceration is also one of the causes of rectal cancer. Tumor polyps can become cancerous. Adenomas can be divided into three types: tubular adenomas, villous adenomas, and mixed adenomas. Tubular adenomas have a high incidence rate, and villous adenomas have a high canceration rate.

The above is an introduction to the common causes of rectal cancer. I believe that everyone should have a certain understanding of it through the above introduction. If you want to know more about rectal cancer, please consult online experts.
