CA 15-3, Serum

CA 15-3 Serum Test: A Tool for Breast Cancer Monitoring.

The CA 15-3 serum test measures a protein in the blood, primarily used to monitor breast cancer progression and treatment effectiveness. It's helpful for those already diagnosed, especially when experiencing:

• Breast lumps

• Changes in breast size or shape

• Nipple discharge

• Skin alterations

While not for screening, it provides valuable insights for treatment management.
