(Imaging is not exact so it can be difficult to tell if there is one or multiple
cysts.) It is standard to wait until
cysts get a certain size (I had read / heard around 7cm) before surgically removing them because most cysts resolve on their own and you don't want to undergo surgery unnecessarily. However, if the one is a dermoid, those don't go away. But, again, imaging is not exact and so it may not be a dermoid.
