With the gradual increase of people’s health awareness and the increasing incidence of breast cancer, “mammography” (mammogram) has gradually entered people’s attention, and the “calcification” found in mammograms has caused people’s anxiety. I’d like to help explain the calcifications found on mammograms. First, what is mammogram equipment, like ultrasound equipment, “mammogram” is a kind of mammography equipment, and the earliest time is by “mammogram” emission of X-rays, we are accustomed to call mammogram, once an expert said “It should not be called “molybdenum target” because now there are molybdenum-rhodium double targets, or in the future there will be other equipment emitting rays, the purpose is the same. We can not because the people call “matches” for “foreign fire” must correct its name. Secondly, what is the meaning of calcification. The reason why mammograms have attracted so much attention is that, up to now, most of the early breast cancers have been detected by “abnormal calcifications” discovered by this equipment. Therefore, people began to pay attention to the “calcifications” seen on mammograms, analyzing and studying what kind of calcifications might be cancerous? What kind of calcifications are not suspected to be cancerous? In the mammogram, the doctor can make a judgment by observing the shape, size and distribution of calcifications in detail. Or do they need to be followed up closely? Or does it not matter? It is not necessary to panic at the mention of “calcification”. The reason for this is that it is important to pay close attention to calcifications that are clustered and pinpoint in size. The reason for this is to be highly concerned about early stage cancer. Based on the above, we hope that this will help you not to panic when you see “calcification” and to operate when you see “calcification”.
