Breast Biopsy Aftercare: Discharge During Breastfeeding

Breast examination wound

Hello Doctor, my wife underwent a breast core needle biopsy yesterday.
However, since she is currently breastfeeding, there is a slight secretion of a whitish fluid from the biopsy site.
Could this be breast milk, or should we return to the hospital for a check-up? Thank you for your response.

More Info

After a breast biopsy, particularly a core needle biopsy, it is not uncommon for patients to experience some discharge from the biopsy site. Given that your wife is currently breastfeeding, the presence of a milky white discharge can understandably raise concerns.
Firstly, it is important to differentiate between the discharge that may occur due to the biopsy and the normal milk production associated with breastfeeding. The milky discharge could potentially be a mixture of breast milk and blood or fluid from the biopsy site. This is particularly true if the biopsy was performed on a lactating breast, as the milk ducts may be affected during the procedure.
In general, a small amount of clear or slightly milky discharge can be normal after a biopsy, especially if the procedure was recent. However, if the discharge is accompanied by other symptoms such as increased redness, swelling, warmth around the biopsy site, or if it has a foul odor, these could be signs of infection or complications, and it would be advisable to seek medical attention.

Here are some key points regarding aftercare following a breast biopsy:
1. Monitoring the Site: Keep an eye on the biopsy site for any changes. Normal healing may involve some tenderness and minor discharge, but significant changes should prompt a visit to the healthcare provider.

2. Hygiene: It is essential to keep the biopsy site clean and dry. Gently wash the area with mild soap and water, and avoid using any harsh chemicals or scrubs.

3. Breastfeeding Considerations: If your wife is breastfeeding, she should continue to do so unless advised otherwise by her healthcare provider. The presence of a small amount of discharge should not interfere with breastfeeding, but she should ensure that the area is clean before nursing.

4. Pain Management: If there is discomfort at the biopsy site, over-the-counter pain relief medications such as acetaminophen or ibuprofen can be used, but it is important to follow the dosage instructions and consult with a healthcare provider if there are any concerns.

5. Follow-Up Care: It is crucial to follow up with the healthcare provider as recommended. If there are any concerns about the discharge or if it persists beyond a few days, returning to the clinic for evaluation is advisable.

6. Signs of Complications: Be aware of signs that may indicate complications, such as increasing pain, swelling, or discharge that is yellow or green, which could suggest an infection.

In conclusion, while some discharge after a breast biopsy can be normal, especially in a breastfeeding context, it is essential to monitor the situation closely. If there are any doubts or if the discharge changes in character or quantity, it is best to consult with the healthcare provider for further evaluation. They can provide specific guidance tailored to your wife's situation and ensure that both her health and breastfeeding are managed appropriately.
