Scattered multiple punctate speckled calcified foci in both breasts may be caused by benign diseases such as breast fibroadenoma and breast cysts, or malignant diseases such as breast cancer. 1. Breast fibroadenoma: If breast fibroadenoma appears in both breasts, there will be high-density, lobulated or ovoid density shadow in mammography or ultrasound, and there may be coarse calcification inside. 2. Breast cysts: patients with breast cysts in both breasts may have round or oval shaped lumps in mammography, and the walls of the cysts may have patchy calcification. 3. Breast cancer: If the patient has breast cancer in both breasts, it may appear as linear, punctate, branched or worm-like calcification in X-ray examination, and the calcified foci may be clustered or distributed along the breast ducts. It is recommended that patients with scattered and multiple spot-like calcification foci in both breasts should consult a doctor in time, and the doctor will determine the cause of the disease through other examination results and clinical symptoms of the patient, and take appropriate treatment measures according to the cause of the disease.
