Breast Pain and Lumps: When to Seek Medical Advice - Breast and Thyroid

Chest tightness or chest pain?


Hello Dr.
Zhou: Before my menstrual period starts, I always experience breast tenderness and can feel lumps on both sides.
After my period ends, the tenderness and lumps go away.
However, this time after my period ended, the breast tenderness (which is more painful than before) and lumps persisted for a week before easing up.
I have also felt several large lumps in my left breast.
Is this normal? Can I take evening primrose oil for breast tenderness? Thank you!

Dear Lily: 1.
It's relatively normal; most of the issues are related to hormonal imbalances in the body.
Just be mindful of any continuously enlarging lumps.
It is recommended to have an annual check-up starting at age 40 (mammography and ultrasound can be alternated for screening).
2.
I'm not clear on the effects of evening primrose oil; it likely varies from person to person!

Breast pain, also known as mastalgia, is a common concern among women, particularly in relation to the menstrual cycle. It can manifest as tenderness, swelling, or discomfort in the breasts, and may sometimes be accompanied by lumps. Understanding the nature of breast pain and when to seek medical advice is crucial for maintaining breast health.

In your case, experiencing breast pain and the presence of lumps before your menstrual period is not uncommon. This condition is often linked to hormonal fluctuations that occur during the menstrual cycle. The breasts are sensitive to changes in estrogen and progesterone levels, which can lead to cyclic mastalgia. Typically, this type of pain resolves after menstruation begins, as hormone levels stabilize. However, if you notice that the pain persists longer than usual or if the lumps remain after your period, it is essential to consult a healthcare professional.

The fact that you have noticed larger lumps in your left breast that persist after your menstrual cycle is concerning. While many breast lumps are benign, such as fibrocystic changes or fibroadenomas, any new or changing lumps should be evaluated by a healthcare provider. It is important to differentiate between benign conditions and potential malignancies, especially if the lumps are hard, irregular, or accompanied by other symptoms such as changes in the skin or discharge from the nipple.

Regarding your question about evening primrose oil (月見草油), it is often suggested as a natural remedy for breast pain, particularly for those experiencing cyclical mastalgia. Evening primrose oil contains gamma-linolenic acid (GLA), which may help alleviate symptoms by modulating hormonal effects. However, while some women report relief, scientific evidence supporting its efficacy is limited. It is advisable to discuss any supplements with your healthcare provider before starting them, especially if you have underlying health conditions or are taking other medications.

In summary, while breast pain and lumps can be related to hormonal changes, persistent or worsening symptoms warrant further investigation. It is crucial to monitor your symptoms closely and seek medical advice if you experience any of the following:
1. Persistent Pain: If breast pain lasts longer than your typical menstrual cycle or becomes more severe.

2. New or Changing Lumps: Any new lumps or changes in existing lumps should be evaluated, especially if they are hard or irregular.

3. Accompanying Symptoms: If you notice changes in the skin of the breast, discharge from the nipple, or any other unusual symptoms.

Regular breast self-exams and routine check-ups with your healthcare provider are essential for early detection of any potential issues. If you have concerns about your breast health, do not hesitate to reach out to a healthcare professional for a thorough evaluation and personalized advice. Your health and peace of mind are paramount, and addressing these concerns early can lead to better outcomes.
