Breast pain, also known as mastalgia, is a common condition that can affect women and, less frequently, men. It can occur due to hormonal changes, especially during the menstrual cycle, pregnancy, or menopause. Other causes may include breast infections, cysts, or injuries. The pain can vary in intensity and may be localized to one area or felt throughout the breast. In most cases, breast pain is not a sign of a serious condition. However, if the pain is persistent, severe, or accompanied by other symptoms like lumps or changes in breast appearance, it is important to consult a healthcare professional for evaluation.
