Colorectal Cancer Deaths Halved by Effective Screening Program in Spain

A 21-year study in Spain's Basque region, published in JAMA Network Open, revealed that a comprehensive colorectal cancer screening program halved disease-specific mortality. This success is attributed to high follow-up rates, with 70% of mailed FIT kits returned and over 90% of positive results leading to colonoscopy, highlighting the public health benefit of effective screening.
