  Purpose
Aromatase(CYP19)inhibitor is one of the major antihormonal drug for breast cancer in postmenopausal women. The variation of CYP19 may affect the effect of aromatase inhibitor. However, the incidence of variation of CYP19 in Korea has not known. Therefore, the investigators want to know the incidence of variation of CYP19 and to assess the effect of these variations of CYP19 to aromatase inhibitor users.

Condition
Polymorphism CYP19 Aromatase Inhibitor
