there is no way the doctor can say that the second cyst is "functional" without surgery. with your first one being diagnosed as cancer, I would be sure that I got some good answers before "waiting" not saying you have cancer again, but in case you do , make that your priority, a baby is a fine thing to want but your life is important also, When you have the scan ask for a CA125 also, Babies need healthy moms, hun, so take care of yourself first. Good Luck
I am sorry to say I did not have the same experience as you but I had to just post I wish you all the best. My girlfriend had trouble getting pregnant and it got very emotional. Add to that cancer and I don't know how she'd have been. All I can say is I think you'll know more after your ultrasound...make a list of all your questions for dr. and go from there. Hang in there!!
