Digoxin administration for 2 weeks prior to surgery.
Digoxin once daily for 2 weeks prior to definitive breast surgery.
No Intervention: No drug administration prior to surgery
Group of participants who will not receive digoxin; however, tissue will be collected at time of definitive breast surgery.
- Changes in HIF-1 protein expression [ Time Frame: 2 weeks ]To evaluate whether two weeks of daily oral digoxin therapy, as compared to no study drug, reduces the expression of HIF-1α protein, measured by immunohistochemistry (IHC), in surgically resected breast cancer tissue obtained from women undergoing lumpectomy or mastectomy for invasive breast cancer.
- Adverse events with digoxin [ Time Frame: 2 weeks ]To assess safety and tolerability of two weeks of digoxin therapy in the pre-surgical setting graded according to Common Terminology Criteria for Adverse Events (CTCAE), version 4.
