I am 55, had 3C ovarian cancer in 2019. Six rounds of chemo (carboplatin/taxol). Complete resection. On Lynparza since then. Ca 125 at 8 since then, went down almost instantly from 4490 after first chemo. My Ca 125 is now at 118, with no apparent reason, and nothing on the CT scan I had. I feel great but I am worried. I had a bout of arthritis when I did the blood test, with pain in my hands, a red swollen finger and a deformed joint. And sinusitis at the same time. I doubt sinusitis had anything to do with my Ca 125, but I am wondering about there arthritis. Anyone know anything? Thanks and best wishes to all, Alexa
