I have been receiving treatment for ovarian cancer for 16 months now, and after chemotherapy and radical debulking surgery I am now taking Niraparib. My CA125 was a steady 27 until I had my first COVID jab, when it started to rise. It went to 33,42,53. Then I had my second jab and it rose to 119 in just over a week. Six weeks after the second jab it is now 232. My CT scans show no changes though so I am wondering if the jab could have affected the CA125, the oncologist is mystified. I just wondered if this has happened to anyone else? Any comments would be much appreciated. Thanks.
