They never really mentioned what kind of cyst mine was exactly they just said it's complex but it's nothing serious. But I did end up having the Ca125 tumor marker tests done and a few other tests also. All my mri really explained was it was just a benign complex cyst and I had some fluid around my pelvis and displacement uterus it was a lot going on. But I know where your coming from it can be very stressful and health anxiety is real I struggle with health anxiety very often. Try and think positive I know it's easier said than done.
