Question

How long after breast cancer treatment is it safe to become pregnant? Will the hormones of pregnancy increase the risk of my cancer coming back?

Answer

Kevin Fox, MD, Medical Oncologist at Penn , responds:

First, the hormonal situation during pregnancy does not appear to increase the risk of cancer coming back. Second, there is no agreed-upon interval from diagnosis to a "safe" time to get pregnant. In general, we recommend that patients wait two years at least before conceiving. Consider discussing your case with a breast cancer specialist.
