<qa>  What is the minimum biological effective dose of atorvastatin required to induce modulation inI. To determine the minimum biological effective dose MBED of atorvastatin required to induce modulation in the proliferation marker, Ki-67, in breast tissue of women who are at high risk to develop breast cancer. We will evaluate pre- and post atorvastatin treatment 4 dose levels expression of Ki-67 in samples obtained via FNA from breast tissue of women at high risk for breast cancer. This specific aim tests the hypothesis that treatment with atorvastatin will induce a decrease in Ki-67.
