Attention meat eaters! Eating too much meat for a long time and eating a high-fat and low-fiber diet will lead to adenomatous polyp, which is a precursor to colorectal cancer. Miss Chen, a 30-year-old diner, not only has three abnormal meals, but also often barbecues and shabu-shabu for dinner. She prefers meat to fried chicken chops 3-5 times a week. It was not until the beginning of last year that she received a physical examination that she found that there were 13 polyps in her intestines. Fortunately, the tests are benign, so she should remove them immediately to prevent future troubles that may lead to colorectal cancer. Miss Chen said that she had an abnormal diet for a long time and was not used to doing health checks in the past. It was not until the company arranged a health check-up at the beginning of the year that she found that there were as many as 13 polyps about 2 cm in size in her intestines, which scared her to never eat meat again after removing the polyps and began to maintain a normal diet with less meat and more fried fruits and vegetables. According to the domestic colorectal cancer screening data released by the National Health Bureau, among the people aged 50-69 with occult blood in stool, nearly 36% were found to have polyps after further colonoscopy, and about 8% were diagnosed with colorectal cancer. Dr. Yang Peizhen, the director of the Health Examination Center, said that the center surveyed more than 800 people who had undergone colonoscopy in the hospital and found that among the 20% polyp patients, more than 70% were adenomatous polyps that needed to be removed. He explained that adenomatous polyp is the precursor of colorectal cancer. Usually, patients with positive fecal occult blood test have large polyps that cause bleeding, but some patients with negative tests may have polyps but have not been detected. The above-mentioned Miss Chen is such a case. Although the incidence of colorectal cancer is the highest among 10 cancers in China, it is easier to prevent than other cancers. Yang Peizhen suggested that the principles of "three lows" (low oil, low salt and low sugar) and "1 high fiber" should be well grasped in daily diet, and the principle of "333" should be maintained in exercise (at least three times a week, lasting 30 minutes each time, and the heart rate reaches 130 during exercise). He emphasized that high-risk groups over the age of 25, such as those who love meat, eat less fibrous food, have a family history of colorectal cancer, familial colorectal polyps or colitis, suggest that people under 40 years old receive colonoscopy/kloc-0 every five years, people aged 40-50 years old receive colonoscopy/kloc-0 every three years, and people over 50 years old receive colonoscopy/kloc-0 every three years.
