RSO (laparoscopically assisted vaginal hysterectomy and right salpingo-oophorectomy), your surgeon was able to see your left ovary
. So one of my questions would be, how did your left ovary
look at the time of your surgery last year? If it looked normal, then you should feel fairly reassured. You are right; most cysts are benign. In fact, with the description of your cyst, I might wait a month and repeat the ultrasound. It may be a cyst of ovulation and be gone next month.
