Hi Andir, I had a large ovarian cyst removed the year before I got bc.The doctor can tell it's a cyst from the ultrasound but they'll often remove it just for safe measure.So if they are calling it a cyst then most likely it is.A hysterectomy is a big operation and needs careful consideration.Once we've had a cancer diagnosis we'll always worry with each new health complaint.You do get abit better at it after many years.I have pneumonia at the moment but ofcourse I'm now worrying it might be lung cancer.Another chest X-ray will hopefully allay my fears.I know how you feel.Big hug,Tonya xx
