Colon Polyp

What Colon Polyps Are

Colon polyps are small growths of extra tissue that form on the inner lining of the large intestine, also known as the colon. These growths can vary in size and shape. Most colon polyps are harmless, but some have the potential to develop into colon cancer over time if they are not found and removed. Because polyps often do not cause symptoms, many people do not know they have them until a screening test is done.

Why Colon Polyps Matter in Cancer Prevention

Finding and removing colon polyps is an important way to prevent colon cancer. Some types of polyps can slowly change into cancer over several years. By removing polyps early, doctors can reduce the risk that cancer will develop. This is why regular screening tests, especially colonoscopies, are recommended for people starting around age 45 to 50 or earlier if there is a family history of polyps or colon cancer.

How Colon Polyps Are Found and Removed

Doctors most often find colon polyps during a colonoscopy. This procedure uses a long, flexible tube with a tiny camera to look inside the rectum and entire colon. If polyps are found, they can usually be removed during the same procedure and sent to a lab for testing. Other tests, like virtual colonoscopy (a special type of CT scan), can detect polyps but do not allow for removal during the test.

Symptoms and Risk Factors

Most colon polyps do not cause symptoms. When symptoms do occur, they may include blood on underwear or toilet paper after a bowel movement, blood in the stool, or changes in bowel habits such as constipation or diarrhea lasting more than a week. People at higher risk include those over age 50, those who have had polyps before, and those with a family history of colon polyps or colon cancer.

What Finding a Polyp Means

Finding a colon polyp does not mean you have cancer. Most polyps are benign (non-cancerous). However, because some polyps can become cancerous over time, doctors take their presence seriously and recommend removal and follow-up care. Your healthcare provider can explain your personal risk and help plan the best screening schedule for you.

Next Steps and Talking With Your Doctor

If you have concerns about colon polyps or colon cancer, it is important to discuss them openly with your doctor. They can guide you on screening options, explain what to expect during procedures, and help you understand your risk based on your age, family history, and previous findings. Early detection and removal of polyps are key steps in protecting your health.
