There is some truth to the idea that breast pain should be alerted to four diseases, but it is not entirely true. When breast pain occurs, it is important to be alert to the occurrence of mastitis, breast hyperplasia, breast cancer, mastalgia and other diseases, because these four diseases are often prone to breast disease, if not timely intervention, the pain symptoms may not only continue to aggravate, but also may lead to sepsis, breast abscess, sclerosing mastopathy and other complications, and breast cancer patients will even be life-threatening. However, since breast pain is also associated with a variety of diseases such as gallstones, gastroesophageal reflux, angina pectoris, Mycobacterium tuberculosis infection, fibroadenoma of the breast, as well as physiological reasons such as pregnancy or changes in hormone levels during menstruation, it is inaccurate to be wary of only four diseases. When encountering breast pain, the correct method is to go to the regular hospital in time to find the cause, if it is due to disease, to actively cooperate with professional doctors for treatment.
