The Breast Cancer Monitoring Panel includes the following tests: 1. CA 15‐3 2. CA 27‐29 3. CEA The Breast Cancer Monitoring Panel is recommended for women currently afflicted with breast cancer, who are breast cancer survivors, or have a history of breast cancer. The Breast Cancer Monitoring Panel can help your physician monitor breast cancer treatment and therapy. Both the CA 15‐3 and CA 27.29 are proteins that are normally produced by breast cells. In persons with breast cancer, the levels can increase. The protein amounts can rise with breast cancer tumor growth and fall with treatment. The carcinoembryonic antigen is a protein that may be present in people with cancer, including breast cancer. The CEA Test measures the amount of this protein in your blood. CEA is normally detected in healthy adults, but at a certain range (see below Normal Range). These three tests can also help your physician offer a more accurate prognosis (or prediction of your health).
