Abstract
Progress in the study of molecular genetics has been revealed that cancer is also a disease of genes, and that some cancers are hereditary. Nowadays, genetic testing is carried out on hereditary cancer, and the patients along with their families are provided with genetic information. 5–10 % of all breast cancer can be attributed to one of several breast cancer familial syndromes, the most common of which is the hereditary breast and ovarian syndrome caused by deleterious mutations of the BRCA1 and BRCA2 tumor-suppressor genes. We executed the genetic counseling to foreign resident in Japan that hoped for the genetic testing and counseling of the BRCA1 and BRCA2. We learnt the necessity of the preparation regarding language, cultural context, and introductions of information resources for consulter of foreign resident in Japan.
