Polyps

Pedunculated Polyp

A polyp starts out as a tiny growth on the lining of the intestine. It can be removed easily and no surgery is needed in that case.

A polyp can be any of the following types when examined under the microscope:

  • tubular adenoma
  • villous adenoma
  • hyperplastic
  • serrated

The villous type of polyp has the greatest potential to turn into cancer.

Polyp appearances

Colon Polyp

Pedunculated Polyp

This type of polyp has the main tumor attached to the wall of the colon by a stalk that is free of tumor. This kind of polyp is easy to detect and remove.
Sessile Polyp

Sessile Polyp

This type of polyp is raised above the lining and the tumor is attached to the lining. It is a little more difficult to detect and remove.
Flat Polyp

Flat Polyp Outlined

Flat Polyp

This type of polyp is hard to detect and hard to remove. On top of that, it has a tendency to lead to a faster spreading cancer than other polyps. The outline in the bottom picture shows the flat polyp more clearly. It is cases like these in which a skilled and experienced gastroenterologist can make a difference between life and death.

 

Colon Cancer

Colon Cancer
If a polyp is allowed to grow, many of them can turn into cancer, as shown at left. Surgery is needed to remove this kind of tumor, and cure is not guaranteed. Colon cancer is essentially a preventable disease that affects both men and women. For the prevention of colon cancer, colonoscopy and removal of polyps like the ones above is the accepted method of choice, despite the inherent risk of a procedure.
