If a Jewish woman has cancer, is it acceptable for her to freeze her eggs so she can still have children?

If this question is not just hypothetical, I wish a refuah sheleimah, a complete healing to the person the questioner is writing about.

As a rabbi, it is always nice to get a question which can be answered with an unequivocal YES.  

One might follow-up with questions about IVF or other assistive reproductive techniques which would be required to turn those frozen eggs (or embryos-depending on methodology) into healthy children.  The answer to those questions would also be yes!  As Jews, we strongly support the creation of new life and new Jewish babies.  The Conservative Movement even has a rabbinic paper encouraging families to have more children than they might otherwise consider.

I wish you much success with treatment, recovery and family-building--all in their proper time and place.  I pray that you and your family will have the strength and patience to journey successfully through this challenging time.  Know that their is a light at the end of the tunnel and I commend you for thinking about your future, even when one might be afraid to imagine that far ahead!
