Can adenomyosis raise CA-125?

Yes—adenomyosis can be associated with a raised CA-125. CA-125 is a nonspecific marker that can rise with inflammation and irritation in the pelvis, and adenomyosis involves endometrial-like tissue within the uterine muscle that can drive chronic inflammation, heavy bleeding, and pain.

That said, an elevated CA-125 does not diagnose adenomyosis on its own, and it also doesn’t tell you how severe adenomyosis is. CA-125 can be elevated for a range of gynecologic and non-gynecologic reasons, and it may also be higher when adenomyosis overlaps with endometriosis (which is common).

If you’ve had a high CA-125 and symptoms like heavy periods, severe cramps, or ongoing pelvic pressure, our team can help you put that result in context and focus on the right next step—typically a symptom-driven evaluation with high-quality imaging (ultrasound and/or MRI) and a plan tailored to your goals, including fertility and long-term relief.
