I think cysts are pretty common. From my mid-teen years on I had fibrous cysts. They came & went and were unrelated to the cancer I had in my 40's. I used to work with a woman that had numerous fluid filled cysts removed.
I've gotten pretty picky in my old age. Not to offend but frankly that comment about "your body telling you, you are ready to have kids" would have made me find another doctor.
