my sister just had one removed. is your mom pre or post-menopausal? they are more likely to be malignant if they are post-menopausal. what kind of cyst is it? is it a dermoid?

I cant answer your question but I'm really sorry to hear that. Something similar happened with my mum. She had a supposedly benign cyst in her ovaries that wouldn't be a problem. One year later and she barely had the strength to walk all because of that "benign" cyst. Thankfully it wasn't cancer and it was removed and she quickly returned to her normal self. I'll be praying the same outcome for your mum.

Let's hope she doesn't...I hope she gets better after the surgery :)

The fact that it has filled with fluid and grown doesn't indicate cancer. If it was actually benign in the beginning it could very well still be. I hope it works out and I know you will worry, that is normal. Good luck to you and your family.
