What is a CA 125 OVARIAN CANCER MARKER?

The CA 125 Ovarian Cancer Marker test is a blood test that measures the level of CA 125, a protein often elevated in ovarian cancer and some other conditions. It is primarily used to monitor treatment response, detect recurrence, and sometimes assist in diagnosis when symptoms or imaging suggest ovarian cancer. While not specific enough for general screening, it is a valuable tool for women at high risk or those already diagnosed, guiding clinical decisions in gynecological oncology.

FAQs

Why is this test done?

It helps monitor ovarian cancer treatment, detect recurrence, and sometimes assist in diagnosis when symptoms or imaging suggest ovarian cancer.

What conditions can this test detect?

What does a high level mean?

Elevated CA 125 suggests possible ovarian cancer but can also occur in benign conditions.

What does a low level mean?

Low or normal levels usually indicate absence of ovarian cancer, but results must be interpreted with other tests.

Can pregnancy affect the results?

Yes, pregnancy may slightly elevate CA 125 levels, requiring careful interpretation.

Can other cancers raise CA 125?

Yes, cancers of the uterus, fallopian tubes, pancreas, and breast may also elevate CA 125.

Is this test suitable for screening healthy women?

No, it is not recommended for general screening due to lack of specificity.

What happens if the sample is contaminated?
