Certain ethnic groups seem to have less access to cancer genetic counseling. Our study was to investigate the participation in cancer genetic counseling among migrant breast cancer patients of Turkish and Moroccan origin. Hospital medical records of Turkish and Moroccan and of a comparative group of non-Turkish/Moroccan newly diagnosed breast cancer patients were studied. All women were diagnosed between 2007 and 2012. Eligibility for genetic counseling was assessed with a checklist. A total of 156 Turkish/Moroccan patients were identified, and 321 patients were assigned to the comparative group. About one third (35 %) of the Turkish/Moroccan patients fulfilled criteria for breast cancer genetic counseling, compared to 21 % of the comparative group (P = 0.001); this was largely due to a relatively young age at diagnosis in the migrant group (26 % <40 years vs 5 % in the comparative group, P = 0.0001). Uptake of genetic counseling among eligible patients was 47 % in the migrant group and 56 % in the comparative group; differences in uptake were seen among the patients diagnosed before 40 years of age (48 % in the migrant group vs 81 % in the comparative group; P = 0.021). When adjusted for age at diagnosis, ethnicity was associated with discussing referral to genetic counseling and its actual uptake. The Turkish/Moroccan ethnicity appears to be associated with a lower uptake of genetic counseling, mainly caused by the lower uptake in the young age-group. The major barrier to participation in genetic counseling seems to lie within the referral process.
