My daughter is 28 and not pregnant. But, she is planning to have children and I am wondering about this. She was diagnosed with a golf ball size brain tumor in her cerebellum when she was twelve. She was followed by a brain tumor clinic at a children's hospital until she was 21. We never had it biopsied and it did not grow all those years. The Neuro Oncologist that followed believed her headaches which triggered the cat scan that found the tumor were unrelated and coincidental. She is very healthy. I am worried that pregnancy hormones could cause problems. Any expert have any information about this or recommendations? She is concerned as well. I am wondering where someone with this knowledge could be found? We live in the Atlanta area.
