CA 15-3 Cancer Antigen

What is the purpose of this test?

Breast cancer is the second most common cancer diagnosed in women. CA15-3 is a normal part of healthy breast tissue, but when breast cancer cells are growing they discard the CA15-3 protein- increasing its level in the blood. Generally, the CA15-3 Cancer Antigen test is used as a tumor marker to monitor treatment and determine recurrence of metastatic breast cancer, though it may be used to track certain other cancers of the lung, pancreas, liver, colon or ovaries.

Who should be tested?

Breast cancer survivors, or those currently undergoing treatment for metastatic breast cancer may benefit from this test, or those with certain other cancers of the lung and ovaries.
