Rosuvastatin to Lower Circulating Tissue Factor Bearing Microparticles in Metastatic Breast Cancer

Since no one knows which of the study options are best, participants will be "randomized" into the following study groups: Group 1 (regular dose of rosuvastatin) or Group 2 (higher dose of rosuvastatin).

Participants will take 1 pill of rosuvastatin every day for 4 weeks. Each 4 week period is called a cycle.

Participants will have a physical exam at baseline, on day 1 of starting rosuvastatin, and 2 month visits. Laboratory tests will be taken at baseline, on day 1 of starting rosuvastatin, 6 weeks and 2 months.
