Recurrence and oral contraceptives?

Page last modified on: July 23, 2008

Question from IlkeG: Why would someone with HR-negative breast cancer need to worry about not taking birth control? It would seem it doesn't apply. I'm confused.

Answer —Kathy Miller, M.D.: For many women who continue to have regular menstrual periods after their treatment for breast cancer, having an effective means of contraception is very important. With modern oral contraceptives, the doses of estrogen are very low and are less than pre-menopausal ovaries make naturally. There should be no concern about an increased risk of recurrence or new breast cancers with current contraceptives, including oral contraceptive pills. That is especially true for women whose initial breast cancer was ER-negative.

On Wednesday, November 19, 2005, our Ask-the-Expert Online Conference was called Hormone-Receptor-Negative Breast CancerKathy D. Miller, M.D., Marisa Weiss, M.D., and moderator Jennifer Armstrong, M.D. answered your questions about a wide range of issues related to hormone-receptor-negative breast cancer.
