Summary
This is a phase II study which will enroll 20 postmenopausal women who are at high risk for
breast cancer development. The goal is to determine whether a one-year intervention of
high-dose vitamin D at 2 different doses (20,000 IU weekly or 30,000 IU weekly) will increase
circulating blood levels of vitamin D and to obtain preliminary data on the biologic effects
of vitamin D for breast cancer prevention.
