Mammography, a plain x-ray technique, is designed for breast examinations. The breast is placed on x-ray plate and gently pressed. The compression, although uncomfortable, greatly improves the visibility of abnormalities. Mammography, as a screening tool, has been found to save many lives. Mammography plays a central part in early detection of breast cancers because it can show changes in the breast up to two years before a patient or physician can feel them. Digital mammography is a new type of breast cancer screening.
It is done the same way as a regular mammogram. But instead of storing the images on film, a digital mammogram records and stores the images on a computer. Digital mammography may be better than film mammography at finding cancer in women younger than 50 and women with dense breast tissue
