The current New Zealand Bowel Screening Programme (BSP) is inequitable. At present, just over half of bowel cancers in Māori present before the age of 60 years (58% in females and 52% in males), whereas just under a third of bowel cancers in non-Māori are diagnosed before the same age (27% in females and 29% in males). The argument for extending the bowel screening age range down to 50 years for Māori is extremely simple-in comparison to non-Māori, a greater percentage of bowel cancers in Māori occur before the age of 60 years (when screening starts). Commencing the BSP at 50 years of age for Māori with high coverage will help fix this inequity. In this paper we review the current epidemiology of colorectal cancer with respect to the age range extension for Māori.
