Patients will also be asked to give a blood/DNA sample which will be stored for possible further testing for the presence of cancer related genes that are known nor or discovered in the future. Patients will also receive a mammogram that will be reviewed by study officials. Side effects will be monitored every 2 months for one year, between visits to the clinic. A follow-up visit will be conducted at the 6 month mark and includes a physical exam, blood work, health and wellness surveys) A follow-up visit will be performed at the 1 year mark and includes a mammogram, gynecological exam, physical exam, blood work, health and wellness surveys.
