Breast tenderness is caused by hormonal changes, which is normal; however, if there are lumps in the breast, please consult a general surgeon or a breast specialist for evaluation.

Breast pain, particularly in relation to the menstrual cycle, is a common concern among women, especially those in their reproductive years. It is essential to understand that breast pain, also known as mastalgia, is often linked to hormonal changes that occur during the menstrual cycle. In most cases, this type of breast pain is not indicative of breast cancer.

Before menstruation, many women experience breast swelling and tenderness due to hormonal fluctuations, particularly the increase in estrogen and progesterone levels. These hormones can cause the breast tissue to retain fluid and become more sensitive, leading to the sensation of fullness or pain. It is not unusual for breast pain to be unilateral (affecting one breast) or bilateral (affecting both breasts), and it can vary in intensity from cycle to cycle.

Regarding the presence of a movable hard lump in the breast, it is crucial to note that many breast lumps are benign (non-cancerous) and can be related to conditions such as fibrocystic breast changes or fibroadenomas. Fibrocystic changes are characterized by lumpy, painful breasts that can fluctuate with the menstrual cycle, while fibroadenomas are solid, non-cancerous tumors that are usually painless and movable.

While breast pain and the presence of a lump can be concerning, it is important to remember that breast cancer is relatively rare in younger women, especially those under 30. In fact, the majority of breast lumps in this age group are benign. Breast cancer typically presents with other symptoms, such as a persistent lump that does not change with the menstrual cycle, changes in the skin or nipple, or unusual discharge from the nipple.

However, it is always wise to err on the side of caution. If you notice any persistent changes in your breasts, such as a lump that does not go away after your menstrual cycle, significant changes in size or shape, or any unusual discharge, it is advisable to consult a healthcare professional. A doctor may recommend imaging tests, such as a breast ultrasound or mammogram, and possibly a biopsy if there are concerns about the nature of the lump.

In summary, breast pain before menstruation is typically a normal physiological response to hormonal changes and is not usually a sign of breast cancer. However, any new or unusual breast symptoms should be evaluated by a healthcare provider to rule out any serious conditions. Regular breast self-exams and awareness of your breast health are essential, as they can help you identify any changes early on. If you have concerns about your breast health, do not hesitate to seek medical advice for peace of mind and appropriate care.
