Dear OncoLink "Ask The Experts,"
Kevin Fox, MD Assistant Director, Clinical Affairs and Associate Professor of Hematology/Oncology at the Abramson Cancer Center of the University of Pennsylvania responds:
It is presumed that estrogen-sensitive breast cancers will be sensitive to all forms of estrogen with few exceptions. No form of estrogen is safer than another. There can be large increases in estrogen secretion with pregnancy. I personally think it is pretty risky.
