In recent years, there has been an increase in the number of colorectal cancer cases caused by the deterioration of colon polyps. This kind of colorectal cancer, which used to belong to the elderly, is now quietly “targeting” young people in their 30s. Some experts point out that if colon polyps can be prevented early, the occurrence of colorectal cancer can be completely avoided. 4 types of colon polyps are most likely to be cancerous: Colon polyps are elevated lesions on the surface of the colonic mucosa that protrude into the intestinal cavity, mostly in the rectum and sigmoid colon, and can also be widely distributed throughout the colon. Endoscopy is the best way to diagnose colon polyps because there are no obvious signs and symptoms of colon polyps. The cancer rate of colon polyps is related to the tissue type and size of the polyps. Generally speaking, adenomatous polyps have a higher cancer rate, with adenomas larger than 2 cm, the cancer rate is greater than 50%. Experts point out that polyps with large size, polyps without tips, polyps with multiple polyps, polyps with flat shape or lobulated polyps are more likely to become cancerous. But no matter what kind of colon polyps, once found, patients should not take it lightly, and should take treatment measures, or regular review, and pay close attention to the dynamics of the lesion. As a digestive system lesion, colon polyps are closely related to dietary habits, and the number of young people getting colon cancer in their 30s is increasing, mainly because modern people are accustomed to “two highs and one low”, i.e. high fat, high protein and low dietary fiber diet, plus too little exercise. Processed foods such as cured and smoked foods are also “regular” on people’s dinner table today, which often contain certain cancer-causing ingredients. For this reason, a light diet, more dietary fiber-rich coarse grains, fresh vegetables and fruits, less meat and seafood, fried and smoked and too spicy stimulating food, to maintain good bowel habits, but also to stop smoking and limit alcohol, etc., to help prevent the production of colon polyps. For patients who have been found to have colon polyps, regular routine checkups are also an important measure to detect polyps that are cancerous.
