Many women experience breast pain before each menstrual period, but what exactly is the cause? Mild breast pain may be due to changes in hormones within the body and is considered a normal physiological condition. Of course, it could also be caused by diseases, such as the commonly seen fibrocystic breast changes, which result in cyclical breast pain associated with the menstrual cycle. There are also other diseases that can cause cyclical breast pain, which should be taken seriously. Especially in cases of severe pain, where even slight touch causes significant discomfort, it is advised to seek timely medical examination at a hospital.
