Breast pain can be detected by color Doppler ultrasound, magnetic resonance imaging and molybdenum target, so as to find out the cause. When there is pain in the chest, you can first check whether there is a lump in the chest. You can go to the breast surgery in the hospital for breast color ultrasound examination, and you can observe the shape of the breast lump through color ultrasound. Blood flow in and around the clavicle, axillary lymph nodes, lumps, breast lumps and small changes can be found, which can play a good screening effect, and abnormal calcification points in the breast can be found, which can be checked by magnetic resonance imaging. Through magnetic resonance imaging, we can know the size and appearance of breast tissue, whether the breast implant is complete, whether there is inflammation or infection in the breast, whether there is abnormality in lymph nodes and whether it may cause chest pain. Mammary molybdenum target X-ray examination can also be performed during the examination, which is a non-invasive examination and can clearly show the calcification of breast. Breast nodules and masses can be shown by mammography.
