The American Society (ACS) recently released an updated guideline for colorectal cancer screening (/cancer/colon-rectal-cancer/detection-diagnosis-staging/acs-recommendations.html). Among the major guideline changes, the new recommendations begin screening at age 45 (as opposed to age 50) for people at average risk for developing colorectal cancer.
For people of average risk, the ACS lowered the age to start screening after analyzing data from a major analysis led by ACS researchers (/latest-news/study-finds/sharp-rise-in-colon-cancer-and-rectal-cancer-rates-among-young-adults.html). This analysis revealed that new cases of colorectal cancer are occurring at an increasingly alarming rate among younger adults. After reviewing this data, experts on the ACS Guideline Development Committee concluded that a beginning screening age of 45 of adults of average risk for developing colorectal cancer will result in more lives saved.
