Are you a breast cancer survivor who happens to be childless?

I do have kids so I'm not able to comment on childless by choice or by circumstance but it didn't happen until my late 30s.  I had a bad miscarriage first off which could easily have made me infertile and I also went through IVF for 18 months to get pregnant with my second child.  I remember the pain of everyone else getting pregnant.  And breastfeeding when the babies came was always a nightmare.  So, I do wonder about those things.  I am also one of the few in my close circle of friends who does have kids - most are childless by choice, and sometimes I have to admit that I envy their freedom (and spare cash).
