Polyps in Your Colon?

For those of you who have been given the news, "You have polyps in your colon", you might be having a great deal of questions out there as to what this means? Do you have colon cancer? Could this happen again? Fortunately, there is a lot of information out there regarding polyps in your colon and, as with many medical issues, knowledge can give you power.

Colon polyps are small collections of cells that occur on the inner aspect of the colon. They can be on a stalk or be flat or somewhere in between. Colon polyps can be pea-sized or the size of a large marble or golf ball. They can also be completely and forever benign or they can convert into colon cancer. The problem is that doctors cannot tell which polyps will always be benign and which ones will turn into cancer. This is why colon polyps that can be removed during colonoscopy are removed at the time the procedure is done.

Polyps in colon can develop in just about anyone. Those who are fifty years of age or older, are overweight, eat a high fat diet, don't get enough fiber in their diet or are a smoker are at higher risk of getting polyps in colon. Those with family histories of colon cancer or colon polyps are also at higher risk of developing colon polyps.

Will you experience any symptoms with a colon polyp? Probably not, but there are a few signs and symptoms you need to be aware of because you could have colon polyps or colon cancer. Some of these symptoms include:

  • Bleeding after having a bowel movement. This kind of bleeding shows up as streaks of blood on the toilet paper after you wipe. If you have this, you could just have hemorrhoids but it is still a good idea to have it checked with a colonoscopy. Even people with hemorrhoids can also have polyps in colon tissue.
  • Blood mixed in with your stool. This can be red blood-streaked stool or can be maroon-colored stool or even black stool. The blood turns black if it sits among the stool for a period of time so black stool is important to watch for.
  • Narrow stool, constipation or diarrhea. This means that just about any change in your stool habits should spur you to have your colon checked. Other things can cause a change in the stool which can be addressed once colon cancer is ruled out.
  • Pain in the abdomen or complete blockage of your stool. This can happen if you have very big polyps in colon and means you need to see the doctor sooner rather than later.

Why do we get Polyps?

Most polyps you'll find on your colon are not cancerous but they are a result of cell growth that has gotten out of control. The "out of control" part of the colon is the lining of the colon, which is why the polyps usually stick out into the lumen of the colon. The healthier cells of the colon grow in an organized fashion and do not divide on their own as do cancerous cells. Polyp cell growth is out of control but it is not to the extent that cancer grows. If the polyp grows long enough, however, the cells can grow wildly out of control and will no longer be polyps in colon but will be full-blown colon cancer. The wild growth of these polyps and of colon cancer occurs because the genes within the polyp are abnormal and don't respond to normal inhibiting growth factors.

Types of Colon Polyps

There are three basic types of colon polyps. Let's take a look at these three types:

  • Hyperplastic polyps. These represent a third or so of total colon polyps. They occur primarily on your left side and inside the rectum. They tend to be small, about a half centimeter and are hardly ever cancerous.
  • Adenomatous polyps. These represent about two-thirds of polyps. People develop cancer most from this kind of polyp. On the other hand, few of these types of polyps actually turn into cancer.
  • Inflammatory Polyps. These are polyps found in people who have inflammatory colitis of some kind. They have a minor risk of turning into colon cancer and are relatively rare.

Inherited Syndromes related to Polyps

Some families have diseases within the family that contribute to members who get colon polyps and colon cancer. They are not common but if you are a member of that type of family, you need to be checked out relatively frequently for polyps on your colon.

  • Familial adenomatous polyposis. This is a genetic disorder where individuals afflicted with this can develop up to many thousands of polyps, beginning as a teenager. You have practically a hundred percent chance of getting colon cancer if you do not have the polyps treated, which may mean removing a segment or more of the colon. You can have genetic testing to see if you have the disease, especially if other family members are afflicted. You can also get small bowel cancer, even duodenal cancer.
  • MYH-Associated Polyposis. It is similar to familial polyposis syndrome in that you get polyps early in age and have a high colon cancer risk. This is a disease we don't know much about; however, genetic testing is available that tells you if you are at risk for this uncommon disease.
  • Gardner's syndrome. This is not a very common disease. Polyps develop in the small and large bowel and can get noncancerous tumors in other body parts. It can affect the skin, bone and abdominal tissue.
  • Lynch syndrome. This is an inherited form of colon cancer but colon polyps are not a big part of the disease.
  • Peutz-Jeghers Syndrome. This involves individuals who develop an abnormal amount of freckles and, later in life, develop an increased risk of developing colon cancer.

What do I do about my colon polyps?

It is a good idea to get a colonoscopy, beginning at the age of fifty. If you have polyps, they can be removed through the colonoscope so you just have to have one procedure. Those polyps are checked for cancer and further treatment, including when you have your next colonoscopy, are determined based on the results of the pathology.
