CA15-3 is a normal product of breast cells, however in cancer it is frequently over-expressed. The CA15-3 marker is most widely used for monitoring the response to therapy of breast cancer patients. It is elevated in up to 70% of patients with metastatic disease, however, as it is only elevated in 3% of those with localised cancer there is no role for screening with this marker.
