    FNAC :
    It is a diagnostic procedure sometimes used to investigate superficial (just under the skin) lumps or masses. In this technique, a thin, hollow needle is inserted into the mass to extract cells that, after being stained, will be examined under a microscope. Fine needle aspiration biopsies are very safe, minor surgical procedures. Often, a major surgical (excisional or open) biopsy can be avoided by performing a needle aspiration biopsy instead
    Stereotactic biopsy:
    Lumps or abnormalities in the breast are often detected by physical examination, mammography, or other imaging studies. However, it is not always possible to tell from these imaging tests whether a growth is benign or cancerous.
    A breast biopsy is performed to remove some cells—either surgically or through a less invasive procedure involving a hollow needle—from a suspicious area in the breast and examine them under a microscope to determine a diagnosis. Image-guided needle biopsy is not designed to remove the entire lesion, but most of a very small lesion may be removed in the process of biopsy.
    Image-guided biopsy is performed when the abnormal area in the breast is too small to be felt, making it difficult to locate the lesion by hand (called palpation).
    In stereotactic breast biopsy, a special mammography machine uses ionizing radiation to help guide the radiologist's instruments to the site of the abnormal growth.
    Core biopsy:
    Needle biopsy is also called a 'core biopsy' or Tru-Cut biopsy. It is used more often than a fine needle aspiration. A core needle biopsy uses a slightly bigger needle than the one used for aspiration.The anaesthetic numbs the area and allows the doctor to take a biopsy - a core of tissue from the lump.
    As with the other types of biopsy, the pathologist looks at the sample in the lab to check for signs of cancer. This type of biopsy is useful because the pathologist can see the cells in place within the piece of breast tissue that has been removed. So it is possible to tell a non-invasive cancer (DCIS) from invasive breast cancer with this test. You can't do this with needle aspiration because you are only looking at cells that have been sucked out.
