Looking for reassurance about rising CA-125
Title: Looking for some reassurance about my mom’s rising CA-125 after treatment
Hi everyone,
I’m posting because I’ve been feeling incredibly anxious about my mom and was hoping to hear from others who may have experienced something similar.
My mom was diagnosed with stage IV high-grade serous fallopian tube cancer in 2025, which initially presented with a malignant pleural effusion. She underwent chemotherapy and surgery and responded really well to treatment. Her CA-125 went from 129 at diagnosis to 5, where it stayed for several months.
She’s been receiving Avastin maintenance and just completed her final scheduled treatment. Her CA-125 was 8 in July, but her latest bloodwork showed it had increased to 24.
I know 24 is still within the normal range (normal range is under 35), but the increase from her usual baseline has really frightened me.
The confusing part is that my mom feels great. Her appetite and energy are good, and she’s been doing so well. The only notable change over the past few months was a persistent dry cough, which her oncologist strongly believed was a side effect of Avastin. Her chest X-ray in August was stable, and the cough has mostly resolved.
Her oncologist has ordered a CT scan to investigate the increase, and we’re currently waiting for it to be scheduled.
I’m trying my best not to jump to the worst conclusion, but after watching my mom go through so much, I’m terrified of her having to experience it all again.
Has anyone experienced a CA-125 increase while still within the normal range, particularly during or after maintenance treatment? Did your levels ever stabilize or come back down?
I’m not looking for a diagnosis, just hoping to hear some experiences and find a little comfort while we wait.
Thank you so much for reading. ❤️
