Summary
Brief summary
The purpose of this study is to evaluate whether the timing of breast cancer surgery during a woman’s menstrual cycle affects her ultimate outcome- the likelihood of recurrence of breast cancer or death from breast cancer. This study involves taking a small sample of blood from the woman close to her surgery to evaluate her menstrual phase on the basis of hormones in her blood. The woman will then go on to have whichever treatments for her breast cancer that she decides with her doctor. The woman will be observed for at least 5 years and information regarding her treatment and disease progression will be submitted.
