Yearly FIT home stool test

A simple yearly home test; a positive result needs a colonoscopy.

Early detectionWith your doctor

What studies found

One FIT finds about 74% of colorectal cancers and 23% of advanced precancerous polyps (U.S. Task Force pooled data). In a national program in Taiwan, people offered FIT had about 10% lower colorectal cancer death after six years.

The catch

It misses most precancerous polyps, so it only works as well as other tests when repeated every year.

What to do

Do it every year, and have a colonoscopy within 6 months if it's positive.
