A breast biopsy is usually done after a suspicious lesion is discovered on either mammography or ultrasound to get tissue for pathological diagnosis.[1] Several methods for a breast biopsy now exist.[2] The most appropriate method of biopsy for a patient depends upon a variety of factors, including the size, location, appearance and characteristics of the abnormality.[3] The different types of breast biopsies include fine-needle aspiration (FNA), vacuum-assisted biopsy, core needle biopsy, and surgical excision biopsy.[3][4][5] Breast biopsies can be done utilizing ultrasound, MRI or a stereotactic biopsy imaging guidance.[2][5][4][6] Vacuum assisted biopsies are typically done using stereotactic techniques when the suspicious lesion can only be seen on mammography.[5] On average, 5–10 biopsies of a suspicious breast lesion will lead to the diagnosis of one case of breast cancer.[7] Needle biopsies have largely replaced open surgical biopsies in the initial assessment of imaging as well as palpable abnormalities in the breast.[8]
