Multiple Choice

A positive FOB test most strongly suggests the possibility of which condition?

Fecal occult blood testing looks for hidden blood in stool, flagging bleeding lesions in the lower gastrointestinal tract. A positive result most strongly points to colorectal cancer, since cancers in the colon or rectum commonly shed blood that the test can detect. While other GI conditions can bleed, the link between occult blood in stool and colorectal lesions is the strongest, making colorectal cancer the best conclusion from a positive FOB test. Prostate cancer does not typically cause blood in stool.
