It's so hard to say what may happen. They may want to do a laparoscopic procedure to get a good look at what is there. If it's nothing serious, they may not do anything at all. They may decide to remove only the cyst. They may decide to remove the ovary and the cyst. If they're concerned, maybe they will do a hysterectomy.
We have all been through these surgeries. They are well worth the trouble and recovery to be healthy!
Best of luck to you.
