CA 15-3

Test Details & Description

CA 15-3 is a blood test that measures the level of a protein called cancer antigen 15-3, which can be elevated in certain types of breast cancer. This test is primarily used to monitor treatment response and check for recurrence in patients already diagnosed with breast cancer, rather than for initial diagnosis. It is important to discuss the results with your healthcare provider to understand their significance in your specific situation.
