What causes breast pain in women?

Female breast pain may be caused by various factors. 1. It could be a normal physiological phenomenon, such as before menstruation or during pregnancy, when hormonal changes stimulate breast development, leading to breast pain and distension. 2. Breast diseases are also common causes; for example, mastopathy (fibrocystic breast disease) may be related to endocrine disorders, excessive mental stress, and other factors, manifesting as breast lumps and pain. 3. Mastitis can also cause breast pain and distension, usually associated with bacterial infection, breast trauma, and other factors, presenting as local redness, swelling, and pain. 4. Other conditions such as cardiac abnormalities and breast cancer may also lead to breast pain. If symptoms persist or worsen, timely medical consultation is recommended to identify the underlying cause and initiate appropriate treatment.
