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 arterial calcifications, also revealed by mammogram, increase the risk of heart disease. Calcification of the coronary and brain arteries increase the risk for heart disease and stroke. Additionally, calcification can cause painful joints, lung disease and formation of kidney stones.
