A breast biopsy is a procedure to remove a small sample of breast tissue for laboratory testing. Breast biopsy is a way to evaluate a suspicious area in your breast to determine if it is breast cancer. There are several types of breast biopsy procedures.
A breast biopsy provides a sample of tissue that doctors use to identify and diagnose abnormalities in the cells that make up breast lumps or other unusual breast changes. And the lab report from the breast biopsy can help determine whether you need additional surgery or other treatment.
