Breastfeeding safe after treatment?


Question from Medtech: I was diagnosed with HER2-positive, stage II breast cancer 5 years ago. Went through chemotherapy, radiation, and Herceptin (chemical name: trastuzumab) and have had no evidence of disease since the end of treatment. I'm now pregnant and overjoyed, but am worried about breastfeeding because of the treatment. Is it safe for me to breastfeed?
Answers - Kutluk Oktay, M.D. There's no such evidence that breastfeeding after completing your cancer treatment would hurt the baby. And, in fact, it may have some mild preventative effect for future cancers.
Leslie R. Schover, Ph.D. One thing that women may find interesting is that for a breast that has had lumpectomy and radiation, about a quarter of women are still able to get some breast milk on that side.

On Wednesday, September 10, 2008, our Ask-the-Expert Online Conference was called Fertility and Pregnancy.
