white masses equal cancer?

I recently had 2 adnexa masses removed that were white with blister like clear bubble with pink tinge, and am awaiting pathology report, they also did a peritoneal bx.  i had a hyster @27 yrs old left ovary removed last yr, hemorraghic cyst , and a small residual peice of a ovary that grew these masses they just took.  I am really concerned that it is ovarian cancer, especially since I have been in menopause since last yr surgery.  My ca-125 is negative.  what are my chances all this is benign and can they continue to re-occur now that there are no more ovary?
