A breast biopsy is a medical procedure used to remove a small sample of breast tissue for examination. This test helps doctors determine whether a lump or abnormal area in the breast is benign (non-cancerous) or malignant (cancerous). There are different types of breast biopsies, including fine needle aspiration, core needle biopsy, and surgical biopsy, each varying in technique and invasiveness. During the procedure, local anesthesia is often used to minimize discomfort. The collected tissue sample is then sent to a laboratory, where a pathologist examines it under a microscope. The results can provide crucial information for diagnosis and treatment planning.
