For breast cancer that has spread to other organs, tumor markers that might be checked include carcinoembryonic antigen (CEA), cancer antigen 15-3 (CA 15-3), and cancer antigen 27-29 (CA 27-29). Blood tests for these tumor markers are not used by themselves to diagnose or follow breast cancer.
Based on this information, your doctor may refer you to a specialist or order tests to check for breast cancer or other health problems. The process of diagnosis may seem long and frustrating. It’s normal to worry, but try to remember that other health conditions can cause similar symptoms as breast cancer.
Women who have already been diagnosed with breast cancer: Most doctors agree that not all women with breast cancer need genetic counseling and testing. But counseling and testing is more likely to be helpful if: You were diagnosed with breast cancer at a younger age; You have triple-negative breast cancer

The Breast Cancer Index test is done on your tumor sample from when you are first diagnosed. It can be used to predict the risk of recurrence in the 5 to 10 years after diagnosis in women whose invasive breast cancers are hormone receptor-positive and have not spread to nearby lymph nodes or have not spread to more than 3 lymph nodes.
Dec 5, 2022 · Breast cancer is the leading cause of cancer death in women worldwide. 1 While most breast cancers are sporadic, approximately 5–10% are hereditary. 2 Pathogenic variants in the high-penetrance genes BRCA1 and BRCA2 account for approximately 20% of heritable breast cancer risk. 3, 4 BRCA1 and BRCA2 play an integral role in DNA damage repair by homologous recombination (HR), and germline ...
