A clinical diagnosis of BI-RADS category 2 on mammography suggests that the lesion is a benign calcification and basically does not require special intervention. Mammography has a very good guiding role in screening for calcified lesions in the breast, which cannot be replaced by other examinations. Generally, round, rod-shaped and coarse calcifications are found in the clinic and may be diagnosed as BI-RADS category 2. The main indication is that the corresponding lesions are benign and most of them do not cause clinical symptoms, so there is no need for too much intervention, and regular review of ultrasound or molybdenum target and other follow-up can be done. If breast calcification is found to increase rapidly or develop into vague amorphous calcification during regular review, it is necessary to consult a doctor to confirm the diagnosis of the condition, and after the diagnosis is confirmed, standardized treatment will be carried out under the guidance of the clinician to avoid delaying the condition.
