Breast cancer is often first suspected when a lump or change in the breast is found or when an abnormal area is seen on a mammogram. Most of the time, these findings do not turn out to be cancer. However, the only way to know for sure is through follow-up tests. Learning about these tests and how to interpret their results can help you understand your diagnosis and make treatment choices that are best for you.
This section of Understanding Breast Cancer discusses biopsies (procedures that remove cells or tissue from the breast to check for cancer) as well as tests that help guide which treatments are best for you if breast cancer is found. Our interactive treatment navigation tool for newly diagnosed patients can help you explore the different types of treatments you may have.
