What are the causes of rectal cancer

The occurrence of colorectal cancer is closely related to genetic factors, environmental influences, unhealthy eating habits, chronic intestinal diseases, etc. The combined effect of multiple factors may induce the formation of colorectal cancer.

Genetics is an important cause of rectal cancer, especially for people with hereditary non-polyposis colorectal cancer (HNPCC) or familial adenomatous polyposis (FAP) in their family, the risk of cancer is significantly increased. Environmental factors should not be ignored. Western diets with high fat, high protein and low dietary fiber will increase the accumulation of intestinal carcinogens. Frequent consumption of pickled and grilled foods or long-term alcohol and smoking may also stimulate intestinal cells to become cancerous. From a physiological point of view, obesity, lack of exercise and decreased immunity will increase the probability of cancer. Certain pathological factors such as chronic intestinal inflammation such as ulcerative colitis or Crohn's disease may also evolve into cancer. In addition, the retention of intestinal contents caused by long-term constipation may cause toxins in the feces to irritate the intestinal wall, increasing the risk of rectal cancer.

To prevent colorectal cancer, you should pay attention to your family history and do regular screening, especially colonoscopy. Improving your diet, consuming more fresh vegetables and fruits rich in dietary fiber, and reducing the intake of red meat and processed meat products can help reduce the risk of cancer. Developing good living habits, including exercising more, maintaining a healthy weight, and quitting smoking and drinking, can also effectively reduce the risk of disease. For patients with chronic intestinal diseases, following the doctor's advice on standardized treatment and regularly monitoring the health of the intestine can help prevent cancer.
