Since last year my periods have been irregular. I am 53. I would have a period for a couple of months, then not for a month, then for 3 weeks at a time, then not for 2 months, then finally last month (May) I started for one week very light and went for 3 weeks very heavy, and one week light. I have always had problems with cysts on my right ovary and have always had pain on that side during ovulation. Well, I had a pelvic ultrasound and they told me I had septated cystic mass on my right , 6.4 cm. Of course, I freaked out! My doctor, who is a family medicine doc, told me there's a possibility it may be cancerous. I had the CA125 or whatever blood test today, final results not back yet and I'm scheduled for an MRI in a few days. My CBC, and creatin levels were good. My doctor sent me to a OBGYN who is head of the dept in gyno for my medical team. I am scared to death it's cancer. I haven't really had bloating or stomach issues, but my periods for the last year have been very inconsistent and heavy. Can someone shed some light on this? I have 5 children and 5 grandchildren. I am about 30 lbs overweight and wonder how much that comes into play on these issues.
