CT Colonoscopy scan

This scan is looking for colonic polyps and early indications of possible cancer. Almost all colon cancers develop over a period of 10 – 15 years from tiny polyps which gradually increase in size and eventually turn into a cancer.

As with all cancers, waiting until the cancer causes symptoms such as weight loss, bleeding, or obstruction to the colon means that it is likely to have already spread and cure is frequently impossible.

However, this long process of conversion means that almost all colon cancers are preventable by undergoing an effective means of screening (such as with a CT virtual colonoscopy) for the polyps and if one is found, then removing it.
