Which screening methods can be used to detect colon cancer?

Currently, three types of stool tests are approved by the US Food and Drug Administration (FDA) to screen for colorectal cancer: guaiac FOBT (gFOBT); the fecal immunochemical (or immunohistochemical) test (FIT, also known as iFOBT); and multitargeted stool DNA testing (also known as FIT-DNA).

Which is better cologuard vs fit?

Cologuard is better at detecting cancer than FIT (92% vs 70% for FIT), but the false positive rate is higher. Cologuard has a 12% false-positive rate, and that rate increases as people age. Cologuard is less accurate than a colonoscopy at detecting polyps of any size.

Can I use cologuard instead of a colonoscopy?

Cologuard is not intended to replace diagnostic colonoscopy or surveillance colonoscopy in high-risk patients, including those with inflammatory bowel disease (IBD).

Is stool sample as good as colonoscopy?

Almost 1 in 6 people who use the Cologuard test will have a positive result that suggests the presence of colorectal cancer. They will no doubt worry they have colon cancer while scheduling and preparing for the recommended follow-up colonoscopy.

How does a colon cancer screening test work?
