Polyp

What a Polyp Is

A polyp is an extra piece of tissue that grows from the lining of an organ, such as the colon (large intestine). It looks like a small bump or growth that sticks out from the mucous membrane, which is the moist tissue lining the inside of the colon and other parts of the digestive tract. Polyps can vary in size and shape. Most polyps are benign, meaning they are not cancer, but some types can develop into cancer over time if not removed.

Why Polyps Matter in Cancer Care

Polyps are important because some can become colorectal cancer, which is cancer of the colon or rectum. Detecting and removing polyps early is a key way to prevent colorectal cancer. This is why screening tests like colonoscopy are recommended, especially for people over age 45 or those with higher risk factors such as a family history of colon cancer or previous polyps. Removing polyps during these exams can stop them from turning into cancer.

What Patients Might Experience or Hear

Most polyps do not cause symptoms, so many people do not know they have them. Sometimes, polyps can cause signs like blood in the stool, bleeding on toilet paper, or changes in bowel habits such as diarrhea or constipation lasting more than a week. If you have these symptoms, your doctor may recommend tests to look for polyps or other causes.

How Polyps Are Found and Treated

Doctors usually find polyps during a colonoscopy, a procedure where a thin, flexible tube with a camera is inserted into the rectum to view the colon. Polyps can often be removed during this exam and sent to a lab to check if they are benign or cancerous. Other tests like virtual colonoscopy (a special type of CT scan) or flexible sigmoidoscopy may also be used. Removing polyps early helps prevent colorectal cancer.

What Having a Polyp Does Not Automatically Mean

Finding a polyp does not mean you have cancer. Most polyps are harmless, but because some can turn into cancer, doctors remove them as a precaution. Also, not all symptoms like blood in stool are caused by polyps; other conditions such as hemorrhoids or infections can cause similar signs.

Questions to Ask Your Care Team

If you are told you have a polyp, you might ask: What type of polyp is it? Does it need to be removed? Could it turn into cancer? How often should I have screening tests in the future? Are there lifestyle changes I can make to reduce my risk of polyps or colorectal cancer?

Understanding the Term in Context

When you see the word “polyp” in medical reports or discussions, it usually refers to a growth found during exams like colonoscopy. It is a common finding and often a reason for preventive care. Remember that polyps are not cancer but can be a warning sign to watch for and manage.

Important Safety Note

This information is educational and does not replace medical advice. If you have questions about polyps or your health, talk with your doctor or health care provider. They can explain what polyps mean for your specific situation and recommend the best care.

Next Steps for Patients

If you are due for colorectal cancer screening or have symptoms like unexplained bleeding or changes in bowel habits, discuss with your doctor whether you need a colonoscopy or other tests. Early detection and removal of polyps can help protect your health and prevent cancer.
