The treatment options for adenomatous polyps are limited to removal, according to AmeriPath. Most of the time, doctors remove them relatively painlessly during colonoscopy, using tools through the scope to perform a biopsy. Especially large polyps sometimes require surgical removal.
Adenomatous polyps are abnormal growths intruding into the canal of the large intestine that grow from the intestinal lining, AmeriPath says. Adenomatous polyps are not themselves cancerous, and most never develop into cancer. Their presence increases colon cancer risk, however, as they occasionally become cancerous when they reach larger sizes. These polyps usually cause few if any symptoms, although painless rectal bleeding is relatively common when they are present.
Approximately 50 percent of people over the age of 60 develop adenomatous polyps, and only 6 percent of those with adenomatous polyps develop colon cancer, according to AmeriPath. While age is the most common factor in the risk of developing polyps, various genetic conditions also make them more likely. A person with risk factors for polyps should watch out for changes in routine bowel movements, abdominal cramping, unexplained weight loss or blood in the stool. If these symptoms are present, the individual may need medical attention. A diet high in fiber can help prevent colon cancer developing from polyps.
