Although not generalizable to the entire Brazilian population, our results revealed that even in a highly educated and well-informed cohort there is a strong association between age and income level with genetic testing. These findings expose the real-world challenges for increasing genetic testing coverage in Brazil, where testing is only warranted in the private health system, highlighting the need for health policies to increase test availability for lower income brackets.enGenetic testingMedicineCohortBreast cancerTest (biology)OncologyHereditary CancerInternal medicinePublic healthCohort studyImpact of breast cancer genetic testing in Brazilian patients: insights from the MAGENTA studyarticle
