There are many different colon polyps symptoms. People can have a range of issues from constipation and complete bowel obstruction to no symptoms at all. That is why people have screening tests for colon cancer so that the disease can be caught early and taken care of before it spreads. Screening is possible because colon cancer usually develops from polyps. Colonic polyps are small growths that develop in the inner wall of the colon or rectum. The colon is the last segment of digestive tract. It is also known as the large intestine or the large bowel. While more rare, the polyps can also occur in the rectum, which is just the final section of the large intestine.
The cause of the formation of colonic polyps is not completely known. It is possible for anyone to have polyps. But there are certain populations that are more likely to get a polyp in colon. A person is more likely to have a polyp in these specific cases:
People over 50 years old have a greater risk of having polyps and also colon cancer.
Someone who has had prior polyps will probably have more of them in the future.
If a family member has polyps, a person is more likely to have a polyp.
If a family member has had colon or rectal cancer, they are at higher risk.
Most of the time a polyp in colon will not cause any symptoms. That is why people should be examined for polyps at age 50, regardless of whether or not they are having symptoms or have family members with colon cancer. Some people may need to be tested earlier. A person should start screening ten years earlier than their family member who was diagnosed with cancer. There are several different ways to look for polyps.
The first option for a screening is a sigmoidoscopy. This is an examination of last part of the colon and also the rectum. The second option is a colonoscopy. This exam that uses a long, tubular scope to examine the inside layers of the whole colon and the rectum. In either procedure a biopsy will be done if any polyps are seen. Both procedure require the person to clean out most of their colon so that it can be examined. During a colonoscopy the patient with be given conscious sedation and normally some pain medicine are given for a sigmoidoscopy.
There are several different types of colon polyps and sessile polyp is one type. The sessile polyp is a flat appearing polyp. Other polyps can be pedunculated, which means that they have a stalk. Polyps can also be tubular in shape. All of these types of colon polyps and sessile polyp have the chance to turn into a cancer, which is why they need to be removed before they grow and spread to other tissues. A person does not want to wait until they have colon polyps symptoms, by that time it may be too late and cancer will have already developed.
