Study Summary

The purpose of this research study is to gain a better understanding of the changes that may occur in the breast when a woman uses an oral contraceptive (birth control pill). Some research indicates that women who use birth control pills with lower amounts of estrogen (a hormone in the birth control pill) may have lower breast cell growth than women who use birth control pills with a higher amount of estrogen; this research will examine that in detail.

Primary Outcome

Percent of cells expressing staining for Ki67 will be examined in breast epithelial cells

Interventions

  • DRUG Oral Contraceptive: Ortho-Novum® 1/35
  • DRUG Oral Contraceptive: Ovcon® 35
  • DRUG Oral Contraceptive: Microgestin Fe® 1/20
