This research study is looking at certain medications used to treat breast cancer called aromatase inhibitors.
This study is being done because it has been determined that an aromatase inhibitor is the best way to treat certain types of breast cancer. The effects of exemestane and letrozole, both are aromatase inhibitors with very different chemical compounds, will be studied to try to identify which women are more likely to have certain benefits or side effects from one or the other of these two medications. The researchers will be looking at the women's genes and at the medication's effects on their body.
