Breast Biopsy During Breastfeeding: What You Need to Know - Breast and Thyroid

When it comes to breast biopsies during breastfeeding, there are several important considerations to keep in mind. First and foremost, it is essential to understand the purpose of the biopsy. A breast biopsy is typically performed to determine whether a lump or abnormality in the breast tissue is benign (non-cancerous) or malignant (cancerous). In your case, the ultrasound has indicated a 1.9 cm mass in your left breast, which warrants further investigation.

Breastfeeding and Biopsy Procedures:
1. Types of Biopsy: There are different types of breast biopsies, including fine needle aspiration (FNA) and core needle biopsy. A core needle biopsy is more common for larger masses, as it allows for a larger sample of tissue to be obtained. FNA, on the other hand, uses a thinner needle and may be less invasive, but it might not provide as comprehensive a sample.

2. Impact on Milk Production: If you undergo a core needle biopsy, there may be a small risk of affecting your milk supply temporarily. However, most women can continue breastfeeding after the procedure. The body typically heals quickly, and milk production should return to normal shortly after the biopsy.

3. Milk Safety Post-Biopsy: After a biopsy, it is generally safe to continue breastfeeding. However, if there is any bleeding or if the biopsy site becomes infected, it is advisable to consult your healthcare provider. They may recommend temporarily discarding milk from the affected side until any potential contamination is resolved.
4. Expressing Milk: If you are concerned about engorgement or discomfort after the biopsy, you can express milk from the affected breast. This can help relieve pressure and maintain your milk supply. It is important to ensure that the area is clean and that you are comfortable while expressing.

5. Alternatives to Core Needle Biopsy: If you are looking for alternatives to a core needle biopsy to minimize discomfort, you can discuss the option of fine needle aspiration with your doctor. While FNA is less invasive, it may not always provide sufficient tissue for a definitive diagnosis, especially for larger masses.

6. Post-Procedure Care: After the biopsy, you may experience some tenderness, swelling, or bruising at the biopsy site. It is advisable to follow your doctor's post-procedure care instructions, which may include applying ice packs, taking over-the-counter pain relievers, and monitoring for any signs of infection.

7. Consulting with Specialists: It is crucial to have an open dialogue with your healthcare provider about your concerns regarding breastfeeding and the biopsy. They can provide personalized advice based on your specific situation and help you weigh the risks and benefits of the procedure.

In summary, while a breast biopsy during breastfeeding may raise concerns about milk production and safety, it is generally a manageable procedure. Most women can continue breastfeeding after the biopsy, and expressing milk can help alleviate discomfort. Always consult with your healthcare provider to ensure that you are making the best decision for both your health and your baby's well-being.
