Colorectal Cancer Screening Age 40: 39% Lower Death Risk
Initiating colorectal cancer screening at age 40 can dramatically cut your risk. A pivotal study reveals that starting fecal immunochemical test (FIT) screening for colorectal cancer screening between 40 and 49 could slash mortality rates related to colorectal cancer by a notable 39%. Moreover, early screening also leads to a compelling 21% reduction in the incidence of colorectal cancer. This news, featured on News Directory 3, underscores the critical imperative of early detection, especially given the rising incidence of colorectal cancer among younger adults. The research, conducted in Taiwan, analyzed data from over 263,000 adults, highlighting the considerable benefits of proactive screening. Discover what’s next in potentially saving lives.
Early Colorectal Cancer Screening Cuts Mortality Risk
Updated June 13, 2025
Beginning fecal immunochemical test (FIT) screening for colorectal cancer (CRC) in adults aged 40-49 could significantly decrease mortality and incidence, a new study indicates.The research, focused on colorectal cancer screening, showed a 39% reduction in CRC mortality and a 21% reduction in incidence when screening started before age 50.
The Taiwan-based study, published in JAMA Oncology, analyzed data from over 263,000 adults.Researchers tracked participants who began FIT screening between ages 40 and 49, comparing their outcomes to those who started at age 50. The findings suggest that earlier colorectal cancer detection through FIT screening can lead to improved outcomes.
The study revealed that those who started and continued early screening experienced a CRC incidence rate of 26.1 cases per 100,000 person-years, compared to 42.6 cases in the group that began screening at 50. Mortality rates were also significantly lower in the early screening group: 3.2 deaths versus 7.4 per 100,000 person-years.
Researchers noted that colorectal cancer incidence is rising among younger populations. As the early 2010s, CRC incidence in those under 50 has increased by about 3% annually. One study even reported a 500% increase in cases among children aged 10-14 over the past two decades.
Despite the study’s limitations, including the lack of established age- and sex-specific FIT cutoff values at the start of the early-age screening program, the researchers emphasized the importance of their findings. They believe the results support lowering the recommended age for CRC screening.
Researchers stated that initiating FIT screening at ages 40-49 was associated with a further reduction in CRC mortality and incidence compared with starting screening at age 50. They added that these results provide strong empirical support for lowering the CRC screening age, with substantial public health implications.
What’s next
Further international research is needed to refine global guidelines for colorectal cancer screening, especially for younger adults. the rising rates of CRC in this age group underscore the urgency of reevaluating current screening strategies.
