I'm glad she's seeing an Ob/Gyn.. I think Trudie is right, but we aren't Drs. and it's always best to get a professional opinion. Most of the time they will just disappear on their own. Most of the time they will "monitor" it for a few months to see if it does disappear. And, as Trudie says, I too feel she will be fine. When is her Dr''s appointment? Let us know how it goes.

A nodule is another term for cyst and hers is quite small. Many do resolve themselves but if not they may need to be removed via laparoscope. Over 95% are benign. There is some good information on the health pages (top right) that you may want to look at. I'm sure all will be fine.
