Breast X-ray can be done when you are having your period. Mammography is also known as breast infrared examination, which is used to check breast fibroids and breast lipomas through infrared irradiation of the breast area by professional instruments. However, its detection rate is not very high, and its clinical application is relatively small. There is no strict limitation on the examination time, and the examination during menstruation will not have too much influence on the body and the examination result. Breast infrared examination is less used nowadays, and most of them still recommend breast ultrasound, breast molybdenum target and breast MRI, which have better accuracy and higher detection rate, and can better detect and diagnose breast diseases. There are many different types of breast examinations, so it is recommended to follow your doctor’s instructions to choose the right one for your individual situation.
