Diagnosis
Can adenomyosis raise CA-125?
The short answer
Yes, adenomyosis can be associated with a raised CA-125, a marker that can rise with inflammation and irritation in the pelvis. An elevated result does not diagnose adenomyosis on its own or show how severe it is, and it can have other causes.
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. 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 or tell you how severe it 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, this means 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.

Worried About Your CA-125 Levels?
Elevated CA-125 can be linked to adenomyosis but isn't a definitive diagnosis. Our specialists help interpret your results and guide you toward the right care for your symptoms.
Questions people ask next
All diagnosis questionsWhat does a high CA-125 mean with pelvic pain or an ovarian cyst?
A high CA-125 can occur with endometriosis cysts, normal menstruation, adenomyosis, fibroids or pelvic infection, so it cannot confirm endometriosis on its own. With pelvic pain or an ovarian cyst, your symptoms and imaging help put the result in context.
Is CA-125 useful for diagnosing endometriosis?
CA-125 is not a reliable way to diagnose endometriosis. It can be normal when endometriosis is present or high for other reasons, including other pelvic conditions and benign inflammation, so results usually don’t clarify whether endometriosis is causing your symptoms.
Do I need extra cancer screening with endometriosis or adenomyosis?
No universal extra cancer-screening program is recommended solely for endometriosis or adenomyosis. Additional evaluation may be appropriate based on your personal risk, especially with a strong family history, genetic predisposition or new concerning symptoms.
When is adenomyosis more likely than endometriosis?
Adenomyosis often rises to the top of the list when periods are heavy and painful, with deep, crampy uterine pain that can linger between cycles. An enlarged, tender uterus or certain ultrasound or MRI findings may support it, but endometriosis can also be present.
