There is some variation regarding age at initiation of screening for colorectal cancer between countries.
However, the same age of initiation is generally recommended for women and men within countries.
This recommendation is despite important gender differences in the epidemiology of colorectal cancer.

Professor Brenner and colleagues from Germany explored whether these differences would be relevant regarding age at initiation of colorectal cancer screening.
The investigators accessed population-based cancer registry data from the USA, and national mortality statistics from different countries.
The investigative team looked at cumulative 10-year incidence and mortality of colorectal cancer reached among men at ages 50, 55, and 60 years.
The team found that women mainly reached equivalent levels when 4 to 8 years older.
The investigators observed that the gender differences were remarkably constant across populations and over time.
Professor Brenner's team concludes, “These patterns suggest that gender differentiation of age at initiation may be worthwhile to utilise colorectal cancer-screening resources more efficiently.”
