Colon Polyps

Definition and Facts for Colon Polyps
Colon polyps are growths on the lining of your colon or rectum. Over time, some polyps can become cancerous, and removing polyps can help prevent cancer of the colon and rectum.​
Symptoms and Causes of Colon Polyps
Most people with colon polyps don’t have symptoms, so you can’t tell that you don’t have polyps because you feel well. When colon polyps do cause symptoms, you may have bleeding from your rectum, have blood in your stool, or feel tired because of anemia.​
Diagnosis of Colon Polyps
Your doctor can only find colon polyps by using certain tests or procedures.​
Treatment for Colon Polyps
Doctors treat colon polyps by removing them. Doctors can remove almost all polyps without surgery. In most cases, doctors remove colon polyps during colonoscopy or flexible sigmoidoscopy.​
Eating, Diet, and Nutrition for Colon Polyps
You may lower your chances of developing polyps by eating more fruits and vegetables and eating less fatty food, red meat, and processed meat. Talk with your doctor about getting more calcium and vitamin D.​
