How many is the probability that normal person physical examination discovers bowel polyp

There is no absolute value for the probability of intestinal polyps found in normal people.

The occurrence of intestinal polyps is related to a variety of factors, such as age, family history, etc. For people under the age of 50, if there is no family history of intestinal polyps at home, the probability of individuals suffering from intestinal polyps will be relatively low. But for people with family history of intestinal polyps at home, the probability of intestinal polyps detected by physical examination will be greater. In addition, diet and lifestyle are also important factors affecting the occurrence of intestinal polyps, such as high fat, high protein, low fiber diet and lack of exercise lifestyle are associated with the occurrence of intestinal polyps.
