Introduction
In general, a woman's breasts may slightly increase in size during her menstrual period, but this is temporary and usually returns gradually to normal size. During menstruation, a slight enlargement of the breasts may occur, primarily due to increased levels of estrogen and progesterone in the body, which can lead to this temporary change.

Under normal circumstances, a woman's breasts may slightly increase in size during her menstrual period, but this is temporary and usually returns to normal gradually. If discomfort occurs, it is advisable to seek medical attention promptly. The detailed explanation is as follows:

During the menstrual cycle, women may experience slight breast enlargement. This is primarily due to increased levels of estrogen and progesterone in the body during this time. These hormonal changes stimulate the development of mammary glands and ducts, leading to a mild increase in breast size. Typically, after menstruation ends, estrogen and progesterone levels return to baseline, and the breasts gradually revert to their original size. This fluctuation is considered a normal physiological phenomenon and does not require special treatment.

However, not all women experience noticeable breast enlargement before or during their periods. Due to individual differences, some women may have a less pronounced hormonal response or lower sensitivity of breast tissue to hormonal fluctuations, resulting in little to no change in breast size or sensation around the menstrual cycle.

In daily life, women are advised to maintain a healthy lifestyle, engage in moderate exercise, and wear properly fitting bras, which can help alleviate breast discomfort during the menstrual period.
