What are the common causes of rectal cancer

Among cancer diseases, rectal cancer is also a type. Many people are susceptible to rectal cancer, but they don’t know what causes it. Next, let’s take a look at the causes of rectal cancer .

(1) Dietary factors and the influence of carcinogens are one of the causes of rectal cancer. A high-fat, high-protein diet can increase the amount of methylcholanthrene in feces, which can induce rectal cancer. A reduction in the fiber content in the diet slows down the speed at which feces pass through the intestines, increasing the contact time between carcinogens and the intestinal mucosa, leading to an increased chance of developing rectal cancer.

(2) The cause of rectal cancer is related to precancerous lesions. Familial multiple rectal adenomas have been considered precancerous lesions. If left untreated, the rate of malignant transformation of rectal cancer is almost 100%.

(3) Chronic inflammatory stimulation of the rectum can also lead to the occurrence of rectal cancer. For example, ulcerative colitis, schistosomiasis, etc. can cause repeated destruction and repair of the mucosa and lead to rectal cancer.
