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.
A mass, with or without calcifications, is another important change seen on a mammogram. Masses are areas that look abnormal and they can be many things, including cysts (non-cancerous, fluid-filled sacs) and non-cancerous solid tumors (such as fibroadenomas), but may sometimes may be a sign of cancer.f a mass is not a simple cyst, it is of more concern and might need to be biopsied to be sure it isnât cancer. 1  A cyst and a tumor can feel the same on a physical exam. 2  They can also look the same on a mammogram.
