Mammography is currently the most common method of screening for breast disease. Mammography often reveals calcifications in some breast tissues, which are classified as benign or malignant. Most of the benign calcifications are scattered, with neat, clear edges and uniform densities, but the center is transparent with ring-shaped calcifications, “popcorn”-like calcifications, rut-like calcifications along the blood vessels, short arc-shaped calcifications, etc. For such calcifications, there is no need to cause panic. There are often patients who are worried because of the detection of breast calcification, and even come from thousands of miles to Shanghai for consultation, which is not necessary. In fact, breast calcification does not mean breast cancer, and benign breast calcification accounts for a significant proportion. Most of the calcifications in breast cancer appear as clusters of fine-grained calcifications (i.e. sediment-like calcifications) and calcifications along the ducts, which can appear as short rods, worm-like or branched-like. The correct approach is to ask a radiologist specializing in the diagnosis of breast diseases to evaluate the X-ray film comprehensively and meticulously, and for calcifications suspected to be breast cancer, puncture can be performed under X-ray positioning for early diagnosis. Therefore, women should not be nervous when they find calcification in breast, but should ask relevant experts for further examination and evaluation, and should not scare themselves, which will affect their emotions, life and work.
