Value of Timely Screening

Early detection of colorectal cancer (CRC) has been shown to decrease mortality.1 As such, the current CRC screening guidelines recommend screening in all average-risk patients ≥45 years of age.2-5 Data supporting these recommendations suggest an increase in CRC incidence in individuals aged 40-49 years that is double that of individuals aged 50 to 54 years (1.3% vs 0.5% increase per year from 2008 to 2017) and an increase in CRC mortality in adults younger than 50 years since 2005.3 Despite clear CRC screening recommendations, screening rates are well below the nationwide target;6,7 thus, important opportunities for screening and early detection are being missed.

Early detection of CRC improves survival rates1

The evolution of colorectal adenoma to early CRC typically takes more than 10 years, providing an important opportunity for screening and early detection8,9

Recent updates to guidelines that expand screening to individuals aged 45-49 years means ~19 million more are eligible for screening10,a

Higher rates of screening are associated with a reduction in colorectal cancer incidence and mortality

The study was performed using a dynamic cohort of Kaiser Permanente Northern California (KPNC) health plan members, aged 51-75 years of age, for the years 2000-2015. KPNC is an integrated healthcare delivery organization that serves approximately 4.0 million members in urban, suburban, and semi-rural regions throughout California. The primary outcome was the influence of organized screening on screening up-to-date status, CRC incidence, and CRC-specific mortality. Limitations include that the observational design precludes confirming a direct causal link between the increases in screening and the decreases in colorectal cancer outcomes.


  • Lowering CRC screening age to 45 years is likely to have an impact on CRC incidence and mortality in the group ages 50 to 54 years.3
  • Incidence in this age group is currently increasing, in contrast to the declining incidence in all age groups after age 54 years.3

Only 48%

of the 50 to 54 years old population are up-to-date on screening.1

Estimate based on the US population aged 45-49 as of 2018, adjusted for the reported rates of high-risk conditions and prior screening history for CRC.

Based on people with CRC in stage I, stage IIa, or stage IIb between 2012 and 2018. 

Per American Joint Committee on Cancer’s (AJCC) staging system: Localized = stage I, IIa, IIb. Regional = stage IIc and III. Distant = stage IV.13
