Hello everyone. Hope you are all well. Just joined and hoping I can get some answer for my mum. She was diagnosed with stage 3c serous ovarian cancer and she had surgery and chemo. She was cleared for a year but then she had to have a ct colonoscopy for some bowel issues. The ct revealed a metastases to the liver and lung and a mass back in the pelvic. The bowel was clear. The oncologist ordered a ct scan to confirm and it showed the same. What baffles the doctors and ourselves is the fact that her ca125 is still 3. It's was 195 at diagnosis. She had a pelvic biopsy which came back with dead cells so it was negative. Her ca125 is still 3 so just can't understand how the disease can spread without any rise in her ca125. 3 is even well below the normal ca125. She had a ct 6 months before all this and it was clear so within 6 months it has popped up again and spread so far with a ca125 still 3 through out all this. If the ovarian cancer is back why isn't it producing ca125 marker since its what they use to monitor recurrence. Any idea will be appreciated. Theve started her on chemo again. Thanks
