Calcifications: Calcifications are tiny flecks of calcium â like grains of salt â in the soft tissue of the breast that can sometimes indicate the presence of an early breast cancer. Calcifications usually can't be felt, but they appear on a mammogram. Depending on how they're clustered and their shape, size, and number, your doctor may want to do further tests. Big calcifications â macrocalcifications â are usually not associated with cancer.
It is normal to use lower-energy X-rays (typically Mo-K) than those used for radiography of bones. Ultrasound, ductography, positron emission mammography (PEM), and magnetic resonance imaging (MRI) are adjuncts to mammography.Ultrasound is typically used for further evaluation of masses found on mammography or palpable masses not seen on mammograms.omen whose breast cancer was detected by screening mammography before the appearance of a lump or other symptoms commonly assume that the mammogram saved their lives. In practice, the vast majority of these women received no practical benefit from the mammogram.
