Stool DNA Tests Offer Higher Sensitivity but Lower Specificity Than FIT
Multitarget stool DNA tests show higher sensitivity for colorectal cancer and advanced adenomas than FIT, but with lower specificity and higher costs; further evidence is needed on long-term effectiveness and economic sustainability. (Clinical

FIT Remains Cornerstone of Population-Based CRC Screening
Fecal immunochemical testing (FIT) continues to be the foundation of organized colorectal cancer screening programs due to its noninvasive nature, affordability, and proven mortality reduction, though stool DNA tests may serve as complementary options in hybrid

Multi-cancer blood tests may not match colonoscopy for colorectal cancer prevention
A modeling study found that multi-cancer early detection blood tests offer little opportunity for cancer prevention through precursor lesion removal, raising questions about whether detecting multiple cancers can offset the loss of
