Core Needle Biopsy – Standard way to diagnose, or rule out, breast cancer. A hollow needle is used to remove samples of tissue from the breast and a pathologist studies these samples under a microscope to see if they contain cancer.
Excisional Breast Biopsy – Procedure that removes a noncancerous tumor, such as a fibroadenoma, from the breast.
Lumpectomy – Sometimes call breast-conserving surgery, a lumpectomy is an operation to remove breast cancer while leaving as much normal breast as possible. Some surrounding healthy tissue and lymph nodes are usually also removed, with how much of the breast being removed depending on the size and location of the tumor. It is often an option for women with early-stage cancer.
Mastectomy – A surgery which removes the breast tissue, nipple, and areola, but not all the lymph nodes.
Nipple-Sparing Mastectomy – Removal of the breast due to breast cancer or as a preventative measure known as risk reduction surgery. Through a small incision, all of the breast glandular tissue is removed from beneath the overlying skin and nipple.
Modified Radical Mastectomy – A surgery that removes the entire breast, including the breast tissue, skin, areola, nipple, and most of the underarm lymph nodes.
