Anyone can get polyps, but certain people are more likely than others. You may have a greater chance of getting polyps if you
Are over age 50
Have had polyps before

Most colon polyps do not cause symptoms. If you have symptoms, they may include blood on your underwear or on toilet paper after a bowel movement, blood in your stool, or constipation or diarrhea lasting more than a week.
