A recent study from Taiwan suggests that starting colorectal cancer screening at 40 can cut deaths by 39% compared to waiting until age 50. This finding contradicts current US guidelines, which recommend screening for adults aged 45-75. The research used fecal immunochemical tests (FITs) and found significant reductions in cases among those who began screening earlier. However, experts caution that more research is needed to determine if these results can be applied to other populations.
