Andres,I had the same cancer as you experienced. My CA 125 never had a high count even when I had cancer. So it does not work for me. I had a friend who wanted and did get a PET scan and from what she said I think yes you should push for it. And ask him or her why they did not suggest it. I am told that a CT scan only shows masses and PET scan is much more effective. That is all I know. Let me know how you do please. My prayers and thoughts are with you.
