Hi, I've written in before. I just got the results of my third follow-up ultrasound for a complex predominantly cystic structure in the right ovary - and the doctor says that the cyst has collapsed to a third of the size that it was, and that it's great news because collapsing cysts are not cancerous cysts. I insisted that we follow up 6-8 weeks with another ultrasound. Any info on collapsing cysts not being cancerous? It's great news. I just want to make sure. Thanks for your support.
