Utility of genetic testing (GT) to guide cancer treatment, risk management and prevention, has driven the demand for cancer genetic services. We evaluate the outcomes of the first Genetic Counsellor (GC)-led service in Asia, as a potential model for mainstreaming. GC efforts were significant in addressing barriers, which led to improved uptake and increased carrier detection. Referral pathways and support groups were also implemented to improve access and provide patient support. Our findings highlight the feasibility of a GC-led mainstreaming model that is safe and scalable. Expanding the GC workforce should be a priority in meeting the global demand for GT. (By Ms. Jeanette Yuen, https://jmg.bmj.com/content/early/2025/09/04/jmg-2025-110995 )
