I had surgery to have my ovary removed & have been doing great. Not sure if it was actually necessary to remove it because I don't know if they dissolve on their own but my Dr was scared that it was cancer so he had it removed and tested & Thank God everything was good. The only thing is that my periods are not consistent anymore. I go 8 to 9 months without one then I have one then it can be months again before I have one. But I do enjoy not having them
