I agree with Carm. Get rid of it. I had 2 cancerous lymph nodes. They removed both and surrounding tissue had 'clean edges' a year after the surgery.

I see no other option other than surgery. Masses, cancerous or not very seldom clear up on their own., and you are asking for more problems down the road. This is one can you do not want to kick. I am an ovarian cancer survivor. Because of where your mass is located, I urge you to seek out a second opinion from a gynecologist oncologist as relates to your upcoming surgery. This mass may very well be benign, but it is important to talk with a gynecologist oncologist and get his input as it relates to your current medical history. Most surgeons or gynecologists do not have the additional training or experience to treat possible ovarian cancer, you need a specialist. As carm stated , many ovarian cancers are caught by accident, it is also true that many of these ,are found to be within the earlier stages when most are highly treatable.

I guess the general consensus is to have the surgery. Thank you all for taking the time to answer this question for me. And also thank you CARM for letting me know of other options besides chemo. Nobody has discussed that with me.
Blessings to all of you.

Good luck. I had a total hysterectomy, as I had uterine cancer -- the surgery was not that bad. 3 days in the hospital and I was off work for 6 weeks. My biggest annoyance was the lifting limit. Hope all goes well.
