Recently, 52-year-old Hong Kong powerhouse singer Jacky Cheung revealed to the media that he was found to have an intestinal polyp during a colon exam and had it surgically removed. Afterwards, he confessed that his father and grandmother had both had cancer and was glad that this time it was found in time and did not cause a lesion. He also suggested that we must have regular medical checkups after the age of 50. The polyp is actually a bulging lesion on the surface of the intestinal mucosa. From the perspective of pathology, the types of polyps are mainly adenomatous polyps, inflammatory polyps, hyperplastic polyps, etc. “Depending on the type, the cancer rate of intestinal polyps ranges from 3% to 30%, and most colon cancers are transformed from intestinal polyps.” Among them, adenomatous polyps have a relatively high chance of becoming cancerous. Intestinal polyps are easily overlooked because they generally have no clinical symptoms, and only a small percentage of patients with intestinal polyps have abnormalities such as blood in stool, mucus stool and abdominal pain, and these symptoms often lack specificity, so to confirm the diagnosis of intestinal polyps, we have to rely on colonoscopy and other instrumental examinations. Early diagnosis of intestinal polyps is very important, and studies have found that timely treatment can reduce the incidence of colon cancer by 70% to 90%. High-risk groups need special attention: those who have colon cancer or colon polyps in their family members; those who eat high fat, high animal protein, low fiber and fried food for a long time; those who are older than 50 years old. In addition, the longer you sit, the higher the risk of developing intestinal polyps. It is recommended that these types of people have an annual examination such as electronic colonoscopy, anal finger examination and fecal occult blood to detect colon adenomas with cancer tendency in time. In Europe and the United States, where colorectal cancer is highly prevalent, it is recommended for all people from the age of 50 to have an annual occult blood test on naturally excreted stool and a complete colonoscopy every 5 to 10 years. It is also important to do prevention in life, reduce sedentary, eat less high-fat food, eat more fresh fruits and vegetables and coarse fiber food, exercise for half an hour every day, and the University of California study found that vitamin D helps change intestinal cell growth and 10 minutes of sunlight every day helps prevent cancer.
