What are some easy colonoscopy options?

Noninvasive colonoscopy screenings are just a prescription away, so listen up you reluctant 40% of 50-and-older folks who’ve never been screened for colon cancer. No more excuses.

One noninvasive colonoscopy screening option is a virtual colonoscopy that involves a computer tomography (CT) scan, which is as effective as a traditional colonoscopy. (You still have to do the bowel-cleansing preparation). A newer option is an at-home screening that requires no prep: the DNA methylation test.

Here's how the DNA methylation test works: You put a stool sample (preferably a "complete bowel movement") into a bag and send it off to the lab in the mail. There, they look for a specific gene that, if turned off (i.e., hypermethylated), could be a sign of colon cancer.
