Calcification of mammary fibroids means that high-density calcified spots and foci of calcification are found in mammary fibroids, which are commonly found in two cases: First, calcified foci formed by calcium salt deposition due to local tissue necrosis, which are relatively coarse, patchy or even tubular calcification, considered to be caused by tissue necrosis. Secondly, intra-tumor carcinoma can also appear as calcification foci with dense dot-like distribution. No matter which type of calcification it belongs to, it is recommended to further surgical treatment in time and try to visit the hospital for the doctor’s preliminary judgment. If the possibility of benign is considered to be high, puncture biopsy can be chosen for further treatment according to the results of pathological examination. In most cases, it is recommended to try to choose surgery to remove the tumor and send it for pathological examination, which is the gold standard of diagnosis.
