CA15-3 (Cancer Antigen 15-3) is a glycoprotein antigen commonly used as a tumor marker for breast cancer. It is most valuable in advanced or recurrent breast cancer, where CA15-3 levels are often significantly elevated.
Note: Elevated CA15-3 alone does not confirm breast cancer, as benign conditions such as mastitis, liver disease, or ovarian cysts may also raise levels.
A venous blood sample is collected to measure CA15-3. Results should be interpreted with clinical history and imaging (ultrasound, mammogram, or MRI).
Q1: Does high CA15-3 always mean breast cancer?
A: No. Benign diseases such as mastitis or liver disease can also increase CA15-3.
Q2: Is CA15-3 useful for early breast cancer screening?
A: No. Many early breast cancers show normal CA15-3 levels, so it is not reliable for screening alone.
Q3: How should CA15-3 results be interpreted?
A: Results should be evaluated alongside clinical examination and imaging (ultrasound, mammogram, MRI), focusing on trends over time.
