Summary

This study is being done to look at the difference, if there is a difference between two different doses of Vitamin D and the reduction of joint/muscle pain (arthralgia)that is caused by taking anti-estrogen medications (aromatase inhibitors) by breast cancer patients. The investigators hope to learn if taking a higher dose of Vitamin D is a good way to prevent aromatase inhibitor arthralgia (AIA).
