Mammography is useful to women

  Mammography is a specific type of imaging that uses a low-dose x-ray system to examine breasts. A mammography exam, called a mammogram, is used to aid in the early detection and diagnosis of breast diseases in women.
    An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.

    Mammograms are used as a screening tool to detect early breast cancer in women experiencing no symptoms and to detect and diagnose breast disease in women experiencing symptoms such as a lump, pain or nipple discharge.

    A mammography unit is a rectangular box that houses the tube in which x-rays are produced. The unit is used exclusively for x-ray exams of the breast, with special accessories that allow only the breast to be exposed to the x-rays. Mammography is performed on an outpatient basis.

    During mammography, a specially qualified radiologic technologist will position your breast in the mammography unit. Your breast will be placed on a special platform and compressed with a paddle (often made of clear Plexiglas or other plastic). The technologist will gradually compress your breast.

    Breast compression is necessary in order to:
    Even out the breast thickness so that all of the tissue can be visualized.Spread out the tissue so that small abnormalities are less likely to be obscured by overlying breast tissue.Allow the use of a lower x-ray dose since a thinner amount of breast tissue is being imaged.Hold the breast still in order to minimize blurring of the image caused by motion.Reduce x-ray scatter to increase sharpness of picture.

    You will be asked to change positions between images. The routine views are a top-to-bottom view and an angled side view. The process will be repeated for the other breast.

    You must hold very still and may be asked to keep from breathing for a few seconds while the x-ray picture is taken to reduce the possibility of a blurred image. The technologist will walk behind a wall or into the next room to activate thex-ray machine.
  
    When the examination is complete, you will be asked to wait until the radiologist determines that all the necessary images have been obtained.
