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.
Breast calcifications are small deposits of calcium in the breast. There are two types, macrocalcifications and microcalcifications. In most cases, breast calcifications are harmless. They are usually picked up during a mammogram (breast x-ray). Macrocalcifications are found in about half of all women over the age of 50. They are a natural result of breast ageing.
