My heart goes out to you. So far I am lucky because my ca125 seems to match the results of my PET scans. However, I had a friend pass away with a smilar cancer which she fought for about 7 years. The ca125 did not register correctly the cancer so she was forced to have a PET scan oftern, sometimes every other month in order to see if the chemo worked
I hope this is not your situation. Good luck and keep us informed.
