Colon cancer is a common cancer in
men and women. The reason for virtual colonoscopy is to find colon cancer at an early
stage when it can be treated more easily. Regular colonoscopy is also used to screen for
colon cancer. A long, flexible, lighted scope and tiny camera a put into the rectum and
up into the colon. This lets the healthcare provider look at the colon directly and
remove any polyps that are there. Colon polyps that are found by virtual colonoscopy can
be removed with regular colonoscopy before they turn into cancer.

benefits over regular colonoscopy:

invasive. It usually doesn't need to include any pain medicine or anesthesia.
It takes less time.

the large intestine.

people who are not be able to have regular colonoscopy. In certain cases, it may
be used in people who have problems such as swelling, bleeding, or breathing
It may be able to show areas
of the large intestine that regular colonoscopy can't reach. This may be the case
if part of the intestine is narrowed or blocked.
