Breast Pain During Early Pregnancy: What to Expect

Discomfort during pregnancy

Hello Dr.
Chen, I am currently 5 weeks pregnant with my first child.
For the past few years, I have experienced breast tenderness on both sides before my menstrual period, especially on the right side near the armpit where there is a small protruding lump that is particularly painful.
However, once my period starts, the lump and pain disappear.
Since becoming pregnant, I still have breast tenderness on both sides, and that small lump has become increasingly painful.
Now that my period will not come, I am wondering if I will have to endure this pain until the baby is born.
Is treatment necessary for this condition? Thank you.

Breast tenderness and swelling before menstruation that improves once menstruation begins is likely a case of premenstrual syndrome (PMS).
The lump in the armpit may be accessory breast tissue, which can also contain breast tissue and thus cause symptoms.
During pregnancy, the body is in a high hormonal state, which can also lead to breast swelling and discomfort.
If there are any concerns, it is advisable to visit a breast surgery clinic for evaluation.

More Info

Breast pain during early pregnancy is a common experience for many women, and it can often be attributed to hormonal changes that occur in the body. In your case, since you are currently 5 weeks pregnant and have a history of breast tenderness associated with your menstrual cycle, it is likely that the pain you are experiencing now is related to the hormonal fluctuations that accompany pregnancy.

During early pregnancy, the body undergoes significant changes, particularly in hormone levels. The increase in hormones such as estrogen and progesterone is essential for maintaining the pregnancy and preparing the body for breastfeeding. These hormonal changes can lead to breast swelling, tenderness, and discomfort, which may feel similar to the premenstrual symptoms you experienced before becoming pregnant. The pain can be more pronounced in certain areas, such as near the armpit, where you mentioned having a small lump.

The lump you describe could potentially be a benign condition, such as a fibroadenoma or a cyst, which are common in women of childbearing age. These lumps can become more sensitive during pregnancy due to increased blood flow and hormonal stimulation of breast tissue. However, it is essential to monitor any changes in the lump or if the pain becomes severe or persistent.

In most cases, breast pain during pregnancy does not require treatment and is considered a normal part of the physiological changes occurring in your body. However, if the pain is severe, persistent, or accompanied by other concerning symptoms such as unusual discharge, changes in the lump, or any signs of infection, it is advisable to consult with a healthcare professional. They may recommend an evaluation by a breast specialist or perform imaging studies if necessary to rule out any serious conditions.

It's important to remember that while breast pain can be uncomfortable, it is usually temporary and tends to improve as the pregnancy progresses. Many women find that their symptoms lessen during the second trimester as their bodies adjust to the hormonal changes. Additionally, if you have a history of breast issues or if you are particularly concerned about the lump, seeking a professional evaluation can provide peace of mind and ensure that you receive appropriate care.

In summary, breast pain during early pregnancy is generally normal and often linked to hormonal changes. While it can be uncomfortable, it typically does not require treatment unless there are additional concerning symptoms. Regular check-ups with your healthcare provider can help monitor your pregnancy and address any concerns you may have about your breast health. Always feel free to reach out to your doctor if you have questions or if your symptoms change, as they can provide personalized advice and support throughout your pregnancy journey.
