Breast Cancer is a disease in which cancer cells form in the tissues of the breast. Generally, cancer will form in either the lobules or the ducts of the breast.  With early detection and treatment, many people can lead a normal life.  The CA 15-3 and the CA 27.29 are used to monitor a specific cancer antigen.  Select a breast cancer blood test to help monitor your response to treatment and manage metastatic carcinoma of the breast and more.
