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.
Dense breast tissue appears as a solid white area on a mammogram, and fat appears as a dark area. Mammogram X-rays do not penetrate â or see through â dense tissues as well as they do through fat. So, in women with dense breasts, mammograms may be more difficult to interpret.ense breast tissue appears as a solid white area on a mammogram, and fat appears as a dark area.
