CA 15-3 and CA 27.29 Tumor Markers
(CA 15-3 and CA 27.29)
- Cancer Antigen 15-3 and 27.29
The presence of high levels of the antigens CA 15-3 and CA 27.29 in the blood are tumor markers and indicate advanced metastatic breast cancer. Lower blood levels are also seen with non-cancerous breast disease, and cancer of the colon, lung, ovary, pancreas, and prostate. These tests are not used to diagnose breast cancer, but to monitor disease progression and how well you are responding to treatment.
