CA-125 is a protein biomarker primarily used to monitor ovarian cancer treatment and detect its recurrence. It's also used to screen women at high risk for ovarian cancer. However, CA-125 levels can be elevated in various non-cancerous conditions, including endometriosis, pelvic inflammatory disease, and liver cirrhosis. The test is not specific enough for general population screening. Elevated levels may indicate the presence of ovarian cancer, but further diagnostic tests are usually required for confirmation. Regular CA-125 testing can help track the effectiveness of cancer treatment and detect early signs of recurrence in women previously diagnosed with ovarian cancer.
A CA-125 level below the lower range is generally not a cause for concern. Low levels are typical in healthy individuals and do not indicate any specific medical condition. In fact, lower CA-125 levels are often considered favorable, especially in patients undergoing treatment for ovarian cancer, as it may suggest a positive response to therapy. However, it’s important to interpret results in the context of an individual’s overall health and medical history.
Elevated CA-125 levels (above 35 U/mL) may indicate the presence of ovarian cancer, particularly in post-menopausal women. However, high levels can also occur in other cancers (e.g., breast, lung, colon) and non-cancerous conditions. In women with known ovarian cancer, rising CA-125 levels may suggest disease progression or recurrence. It’s crucial to note that CA-125 alone is not diagnostic; further tests like imaging studies or biopsies are typically needed to confirm the cause of elevation. Always consult with a healthcare provider for proper interpretation of results.
