NCT00318318

Brief Summary

The purpose of this study is to assess the immunological status of patients using Premarin. Premarin use is associated with an enhanced immune status, and possibly even some anti-cancer effect. The researchers will compare the use of Premarin with those not using hormone replacement therapy (HRT) to track the effects of Premarin in reducing the risk of infection and swelling.
