CA 15-3 (Breast Cancer Treatment Response) Blood Test

CA 15-3 (BREAST CANCER TREATMENT RESPONSE) BLOOD TEST

This test measures the levels of CA 15-3 in your blood and serves as a valuable marker for monitoring disease progression and treatment response in individuals already diagnosed with breast cancer. This is not a cancer screening biomarker.

CA 15-3 levels are particularly useful in tracking the course of breast cancer and monitoring treatment effectiveness. Serial measurements of CA 15-3 levels over time can help healthcare professionals assess the response to therapy and evaluate the progression of metastatic breast cancer. A decline in CA 15-3 levels may indicate a positive response to treatment, while an increase in levels may suggest disease progression or recurrence.
