Calcification of breast fibroma is mostly due to calcium salt deposition caused by bleeding and inflammation. Breast fibroma is a common benign breast disease, commonly seen in young women, clinically manifested as painless, mobile breast lumps. Calcification of breast fibroids may be caused by excessive calcium salt deposition due to local inflammation, bleeding and exudation of fibroids, etc. The excessively deposited calcium salt component replaces normal tumor cells, thus resulting in the phenomenon of calcification. If ultrasound or X-ray examination shows more calcification, it indicates that the breast fibroid tumor has been in existence for a long time, and it is necessary to raise vigilance to prevent malignant changes. Calcification of breast fibroids may also have other causes, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy to avoid delaying the condition.
