Macrocalcifications are coarse calcium deposits and are often seen in both breasts. They are most likely due to aging, old injuries or inflammations. Microcalcifications are tiny flecks of calcium found in an area of rapidly dividing cells. Clusters of numerous micro- calcifications in one area can be a sign of ductal carcinoma. About half of the cancers found by a mammography are detected as clusters of microcalcifications.
Mammograms are an important part of a woman's health history.
Being able to compare earlier mammograms with new ones helps doctors evaluate areas that look suspicious. A mammogram is the best method available to detect breast cancer early. However, because a mammogram may miss a cancer that is present, monthly breast self-exam and annual clinicl breast exams are critical. A mammogram can find breast cancer before a lump can be felt but it also may find something that turns out not to be cancer. It is always essential to follow-up with a healthcare provider whenever a mammogram shows an irregularity.
