The pain in the breasts that occurs before menstruation is due to the change in hormone levels in the body that stimulates the expansion of blood vessels in the breasts, causing the pain in the breasts. Due to excessive progesterone, especially during the week before menstruation, it can cause the blood vessels in the breasts to dilate and there is a chance that breast pain will occur. Prior to menstruation, the presence of breast pain can also be accompanied by breast enlargement and breast lumps, which can likewise be irritated due to altered hormone levels. Whenever possible, it is better to go to the hospital and register with the mammography department for a mammogram to rule out the presence of any breast problems. For example, before menstruation, due to excessive exertion, stress, and high mental factors may cause the chances of having breast pain to occur. As much as possible, massage or hot and wet compresses with a 45-degree towel can be used to relieve the pain.
