Analysis of the conditions for applying BRCA genetic testing to women with breast cancer using the Japanese HBOC consortium and the Japanese organization of hereditary breast and ovarian cancer (JOHBOC) registry project database

Consequently, it is imperative to disseminate information to all patients with breast cancer covered by insurance, emphasizing the opportunity for GT, particularly if they have ovarian cancer complications or a family history of ovarian cancer.
