Colorectal Cancer

If polyps are found during the colonoscopy, the specialist would have removed and sent it for microscopic examination - biopsy.

If the biopsy shows that the polyp

1. is cancerous- you may need surgery to remove the portion of the colon where the polyp was removed.
2. is precancerous - (all variety of adenomas) - you will need a periodic colonoscopy at a a regular interval depending on the number of other risk factors you may have -such as family history of colon cancer, number & size polyps you had & how "bad" the precancerous polyps were on biopsies.
3. Hyperplastic- usually of no concern. However, this subject has become a debate point lately & some scientists do believe that these polyps too may be a sign that you are at a risk of developing precancerous polyps later on.

There are other rare types too but that subject is beyond the discussion in this forum.
