I just received news from my family doctor today that after my pelvic ultrasound it has been discovered that I have a 9x9x5 cm mass on my right ovary. Next step priority list for MRI and blood test CA125 in 3 days. I also have a fibroid cyst on the same ovary. I am 53 and premenepausal (sp?) symtoms include lower back pain now 1 yea,r excessive bleeding and very long menstrual cycles, increasingly frequent urination, abdominal pain (stabbing), and fatigue. My Mother died of ovarian cancer when she was 38 .. I was 19. What are the chances in my case that this mass is cancerous? I am really scared as I just received this news hours ago.
