Incidental finding

I had an MRI of my hips due to pain when walking or sitting and they found an ovarian tumor incidentally. I think I am lucky because it was only 5 x 3 cm. I have surgery the second week in August, robotic surgery by a gyn-oncologist. He thinks the tumor is encapsulated and is very optomistic. Here is the thing. I have tried in the past to get a CA-125 test and was always pooh-pooed. I had a feeling that I would get ovarian cancer although there is no family history. Although I could have a benign tumor, I am seventy and I don't think so. I had to push push push my doctors to let me have an MRI because I was getting unable to walk with all the pain which turned out to be severe inflammation in my gluteal muscles where they attach to the trochanters since I have inflammatory arthritis. I finally got my rheumatologist to order an MRI and that is why I am lucky that they found the tumor incidentally. Also my c-reactive protein, which had been normal up to a year ago began to get moderately high. Even with methotrexate which I take we could not get it down, so I believe that it correlates with my ovarian tumor growing. I wonder if anyone else had a high C-reactive protein. Also I am so glad I badgered my doctors until one ordered the scan.
