This paper discusses and provides information on Colon Polyps. A polyp is extra tissue that grows inside the body. Most polyps are not harmful. Symptoms may include constipation or diarrhea for more than a week or blood on your underwear, on toilet paper, or in your stool. Many polyps do not cause symptoms. Doctors remove all polyps and test them for cancer. Talk to your doctor about getting tested for polyps if you have any symptoms, you're 50 years old or older and someone in your family has had polyps or colon cancer.
