It's horrible waiting for scans and results. I was told the MRI helps locate and position the cysts for me however i have 2 on different ovaries. They think they're dermoid and want to remove them. I don't fully know what indicates different routes. Have you had any blood tests? I know for me that's part of the concern. At your age it's most likely cysts. My friend had one removed at 19. I don't know what scans they did but it was so long ago they'd do different investigations any way. I'd be glad they're being thorough and try to distract yourself. I'm not being very good about that myself. You can always speak to your radiologist when you see them about what the notes say as mine helped explain things really well.
