hemorraghic breast cyst

I have had two core biopsies on a cyst in my right breast. The clinic told me not to worry but were unable to confirm any diagnosis. They then called me in at short notice for ultrasound and told me they had found an unusual growth on the cyst. I have just undergone surgery to remove a hemorrhagic breast cyst and am now worried I may have cancer. Has any one else experienced the same.
