More than one-third of Texas women still receive unnecessary breast biopsy surgery
Many women in Texas who are found to have an abnormality on routine mammogram or discover a lump in one of their breasts end up having an old-fashioned surgical biopsy to find out whether the breast abnormality is malignant. ...

Biopsy
A biopsy is a medical test involving the removal of cells or tissues for examination. It is the removal of tissue from a living subject to determine the presence or extent of a disease. The tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy. When only a sample of tissue is removed with preservation of the histological architecture of the tissue’s cells, the procedure is called an incisional biopsy or core biopsy. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration biopsy.
