Breast Biopsy During Breastfeeding: Risks and Considerations - Surgery

Performing a biopsy during breastfeeding?


Hello, Dr.
Hsu.
This week, I discovered a marble-sized hard lump near my left chest close to the armpit.
It is very hard, the skin has turned red, and it is painful.
The lump is movable.
I went to the hospital for a consultation, and the doctor said that a biopsy is necessary to determine whether the lump is a cyst or a tumor.
However, I am currently breastfeeding.
Should I stop breastfeeding in order to have the biopsy, or will having the biopsy while still breastfeeding increase the risk of bacterial infection? Will the biopsy affect my ability to breastfeed? I appreciate your clarification on these questions.
Thank you.

Based on your description, the location of the lump and the redness with pain may not necessarily indicate a breast lump; it could also be a subcutaneous cyst with infection.
It is recommended that you first undergo a breast ultrasound examination before considering further treatment.

When considering a breast biopsy during breastfeeding, there are several important factors to take into account, including the potential risks, the procedure itself, and its implications for breastfeeding.
First and foremost, it is essential to understand that a breast biopsy is a procedure performed to remove a small sample of breast tissue for examination under a microscope. This is often necessary to determine whether a lump is benign (non-cancerous) or malignant (cancerous). In your case, the lump you described as hard, movable, and painful, along with the redness of the skin, warrants further investigation to rule out any serious conditions.

One of the primary concerns for breastfeeding mothers undergoing a biopsy is the potential impact on milk production and breastfeeding. Generally, a breast biopsy can be performed without the need to stop breastfeeding. However, the specific technique used for the biopsy may influence this. For instance, a fine needle aspiration (FNA) is less invasive and may have a lower risk of affecting milk supply compared to a core needle biopsy or an excisional biopsy, which involves a larger incision and removal of more tissue.

In terms of infection risk, while any surgical procedure carries some risk of infection, the likelihood of developing an infection from a biopsy is relatively low, especially when proper sterile techniques are employed. It is crucial to inform your healthcare provider that you are breastfeeding, as they can take additional precautions to minimize any risks. They may also provide specific aftercare instructions to help reduce the risk of infection.

Regarding the concern of bacterial contamination of breast milk, it is important to note that the breast tissue and milk ducts are separate from the area where the biopsy is performed. If the biopsy is done correctly, it should not introduce bacteria into the milk supply. However, if you notice any signs of infection, such as fever, increased redness, swelling, or discharge from the biopsy site, you should contact your healthcare provider immediately.

After the biopsy, some women may experience temporary discomfort or changes in milk supply, but these effects are usually short-lived. It is advisable to continue breastfeeding unless otherwise directed by your healthcare provider. If you experience significant pain or complications, your doctor may recommend temporary measures, such as pumping and discarding milk until you are healed.

In conclusion, undergoing a breast biopsy while breastfeeding is generally safe and should not significantly impact your ability to continue nursing. It is essential to communicate openly with your healthcare team about your breastfeeding status and any concerns you may have. They can provide tailored advice and support to ensure both your health and the well-being of your baby are prioritized. Always follow your doctor's recommendations regarding post-biopsy care and breastfeeding practices to ensure a smooth recovery.
