If you develop a breast lump or other breast change, you may need to have a biopsy. A biopsy is a procedure that removes a sample of cells or tissue from the breast to be tested. The cells or tissue that have been removed are examined under a microscope to look for signs of cancer. A biopsy is generally not painful because a local anesthetic (medicine that blocks pain in the area) is used.
