Some of the breast calcification foci are serious and others are less serious. This requires a comprehensive assessment, as follows: 1. Not serious: If you have had mastitis or breast trauma in the past, the calcification foci are not serious and are caused by infectious factors, so you can go to the hospital for regular review. If the calcification foci are caused by breast cancer, it is necessary to improve the relevant examination, such as breast ultrasound, including puncture biopsy or excisional biopsy, in order to clarify the nature. If cancerous tissues are found, radical resection of the tumor is needed, together with lymph node dissection. Later, chemotherapy, targeted drug therapy, endocrine therapy, radiotherapy, Chinese medicine therapy, etc. may need to be given, and the specific treatment plan needs to be consulted with the competent physician.
