Prevention and risk factors of colorectal cancer

The cause of colorectal cancer is the same as other malignant tumors. It is still not completely clear, but some factors related to the occurrence of colorectal cancer have been noted. It is now believed that the composition of diet plays an important role in the etiology of colorectal cancer. People who usually consume high-fat, high-protein, low-fiber foods usually have a higher incidence of colorectal cancer. This may be because high-nutrition foods with little digestive residue are not conducive to defecation, and food stays in the intestine for too long, so that carcinogens in the food can stimulate the intestinal mucosa for a long time. In addition, inflammation of the colon such as ulcerative colitis, colorectal adenoma and genetic factors are also related to the occurrence of this disease.

How to prevent colorectal cancer

An important way to prevent colorectal cancer is to eliminate known factors that may cause cancer.

⑴ Arrange diet reasonably, eat more fruits, fresh vegetables and other foods rich in carbohydrates and crude fiber, and eat less high-fat and high-protein foods.

⑵ Actively treat existing colorectal diseases such as ulcerative colitis, intestinal adenoma, etc.

⑶ If you have high-risk factors for colorectal cancer, such as familial colon cancer or polyposis, familial multiple myeloma, or ulcerative colitis, you should go to the hospital for consultation or examination regularly to understand your physical condition.

What should we pay attention to in preventing colorectal cancer?

(1) Improve eating habits. Arrange your daily diet reasonably, eat more fresh fruits, vegetables and other foods rich in carbohydrates and crude fiber, appropriately increase the proportion of coarse grains and whole grains in the staple food, and avoid eating too fine or refined foods. Change the habit of eating meat and high-protein foods as the staple food. Eat less high-fat foods, especially control the intake of animal fat. Because high-fat, high-animal protein diets stimulate bile secretion, increase the amount of bile in the intestines, and bile mainly contains bile acid and cholesterol, so the content of bile acid and cholesterol in the feces increases;

(2) Actively prevent and treat intestinal diseases. Such as various polyps, chronic enteritis (including ulcerative colitis), schistosomiasis, chronic dysentery, etc. Intestinal polyps should be treated early. Colon polyps are divided into five categories, namely adenomatous polyps, metaplastic polyps, inflammatory polyps, hamartomatous polyps and others. Among them, adenomatous polyps are true tumor polyps and a precancerous lesion of colon cancer. Therefore, when adenoma is found in the colon, it should be treated, the adenoma should be removed and pathological examination should be performed. It is hoped that it will be removed at the benign adenoma stage to prevent colon cancer. If not treated early, most of them will develop into colon cancer, and the prognosis is poor. In addition, habitual constipation should be actively treated and attention should be paid to keeping the bowels smooth.

(3) People at high risk of colorectal cancer, such as men over 40 years old, patients with familial multiple intestinal polyps, patients with ulcerative colitis, patients with chronic schistosomiasis, and people with a family history of colorectal cancer, should undergo regular checkups and be alert to the warning signs and early symptoms of colorectal cancer, such as changes in bowel habits, alternating diarrhea and constipation, bloody or black stools, and flatter and thinner stools.
