Most ovarian cysts, even complex ones, are benign (non-cancerous). Most
cysts resolve
on their own in 2 to 3 cycles although this is less apt to happen with
complex cysts. If you do not have a family history of ovarian cancer then your lifetime risk is very low, 1.3% per the National Cancer Institute.
If you do need surgery and there is a possibility of cancer, it is best that a gynecologic oncologist do the surgery as they are the experts.
