Colon Polyps Can Cause Cancer


Ever heard of this one disease? Usually we hear disease polyps that grow on the nose, but this one polyp disease is different, it grows in the human colon. Colon polyps or colon polyps, the small clumps of cells formed in the lining of the large intestine (colon). Although colonic polyps are not dangerous, but in some cases can become cancerous over time.

Colonic polyp disease can happen to anyone. People who have a high risk of colon polyps that are older than 50 years, overweight or a smoker, eat foods high in fat and less fiber, and who have a family history of colon polyps or been exposed to colon cancer.

Types of Colon Polyps

1. Adenomatous
Most polyps are included in this category. Although only a small percentage of polyps that develop into cancer, but almost all malignant polyps from adenomatous type.

2. Hyperplastic
Most often occurs in the colon and rectum. Usually has a size <1 / 4 inch (5 mm), this very rare type of polyps develop into cancer.

3. Inflammation
These polyps may accompany attacks of ulcerative colitis or Crohn’s disease of the colon. Although the polyps themselves are not too dangerous, but have ulcerative colitis or Crohn’s disease of the colon increase the risk of colon cancer.

Cause

Actually the majority of polyps do not develop into malignant or cancerous. However, like most cancers, polyps are the result of abnormal cell growth. Healthy cells grow and divide on a regular basis which is a process that is controlled by genes.

Mutations in each of these genes can cause cells to continue dividing even when new cells are not needed. And polyps may form if the division of cells in the colon and rectum is not controlled.

Some polyps can become malignant after a long time. These polyps can develop in parts anywhere in the colon. Size can be small or large and flat (sessile) or shaped like a mushroom or the like attached to the stem (pedunculated). Generally, the larger the size of the polyp, the greater the possibility to develop into cancer.

Symptom

Often these diseases occur without symptoms, colonic polyps are often not detected until the examination by a physician. But, actually there are some signs and symptoms that can lead to colon polyps, which are:

  1. Bleeding in the rectum. Rectal bleeding is not necessarily a symptom of colon polyps, but you should consult your doctor if you experience this condition.
  2. Constipation or diarrhea. These symptoms are also not necessarily a symptom of colon polyps, although changes in bowel habits lasting more than a week such as indicate the presence of colonic polyps.
  3. Pain. Sometimes colon polyps can block the intestines, which can cause constipation, abdominal pain, cramping, nausea, and vomiting.

Consult your doctor if you see the signs and symptoms of the following:

  1.  Abdominal pain.
  2.  Blood in the stool / faeces.
  3. Changes in bowel habits that lasts more than a week.

Prevention & Treatment

Experts suggest screening (examination) regularly, because colonic polyps usually do not cause symptoms. Colonic polyps were found in the early stages can usually be cured completely. With regular screening, may help prevent colon cancer, because the disease is often fatal when detected at an advanced stage.

Pathologist usually must examine a polyp tissue under a microscope to determine whether it has the potential to become cancerous. For this reason, your doctor will likely perform a biopsy (taking a thin layer of tissue for histological examination) in polyps were found.

1. Colonoscopy or sigmoidoscopy
Most polyps can be removed during colonoscopy or sigmoidoscopy using arch (loop) wire that simultaneously cuts and cauterizes the polyp stalk to prevent bleeding. Some small polyps can be burnt or burned with electric current (Electrosurgery). Risk taking polyps (polypectomy) include bleeding and perforation (hole) colon.

2. Operation
Because colonoscopy or sigmoidoscopy are not too safe to be on the polyp is too large, so that often surgery is usually performed using laparoscopic techniques. After the colon polyps removed found, polyps can still grow back in the other surface of the colon, so it is important to closely monitor the condition of the colon.

3. Endoscopic mucosal resection (EMR)
This is done to remove larger polyps by colonoscope. With this technique, a liquid such as saline injected under the polyp to lift and isolate the polyps from the surrounding tissue. This makes it easier to remove larger polyps. With this procedure, you can avoid surgery, but no further study on complications that can arise in this procedure.

4. Appointment of the colon and rectum
The surgeon may perform surgery to remove the entire colon and rectum (total proctocolectomy) in case of familial adenomatous polyposis syndrome (FAP), but this is rarely encountered. Then, in a procedure known as ileal pouch-anal anastomosis, a pouch constructed from the end of the small intestine (ileum) that attaches directly to the anus. This allows it to be able to dispose of feces as normal, though causing more frequent bowel movements with a more watery consistency.
