Diagnosis
Do I need extra cancer screening with endometriosis or adenomyosis?
The short answer
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.
No universal cancer-screening program is recommended solely for endometriosis or adenomyosis, but that does not mean cancer risk should be ignored. Endometriosis is not cancer, and most people with it will never develop cancer. Still, research does suggest an increased risk of certain ovarian cancers, which is why individual risk assessment matters.
Tests such as CA-125 or CA19-9 are not reliable routine screening tools by themselves because they can be elevated for many non-cancer reasons, including endometriosis itself. The right next step depends on your personal risk profile, especially if you have a strong family history of ovarian, breast, uterine, or colon cancer, a known or suspected genetic predisposition, an endometrioma, deep infiltrating disease, or new concerning symptoms.
In those situations, closer evaluation, imaging, follow-up, and sometimes genetic counseling or testing may be appropriate. Our team can help you understand your individual risk and decide whether additional evaluation makes sense.

Questions people ask next
All diagnosis questionsDoes endometriosis increase cancer risk?
Yes, endometriosis is associated with increased ovarian cancer risk, especially clear cell and endometrioid types. The increase is relative to people without endometriosis; absolute risk remains low, and most people with endometriosis never develop cancer.
Can adenomyosis cause cancer?
Adenomyosis is not cancer, and current evidence doesn’t show that it clearly causes cancer. It can sometimes be seen alongside uterine (endometrial) cancer, but research on the relationship between the two is still evolving.
Is there a reliable blood test for endometriosis?
No, there is currently no FDA-cleared blood test that can reliably diagnose or rule out endometriosis. CA-125 and newer biomarker panels cannot confirm it on their own; evaluation starts with symptoms, medical history, and appropriate exams and imaging.
