What is the first-line treatment for a breast abscess?

From the Guidelines

The first-line treatment for a breast abscess is incision and drainage, combined with appropriate antibiotic therapy. For smaller abscesses (less than 5 cm), ultrasound-guided needle aspiration may be performed instead of surgical incision 1. This approach is supported by the 2018 WSES/SIS-E consensus conference, which recommends incision and drainage as the primary treatment for simple abscesses or boils, with antibiotics not needed for simple cases 1. However, in the case of a breast abscess, antibiotics are often necessary to cover common breast pathogens.

The choice of antibiotic should be based on the suspected causative organisms, with dicloxacillin 500 mg orally four times daily or cephalexin 500 mg orally four times daily being typical options for 7-10 days 1. For patients allergic to penicillin, clindamycin 300-450 mg orally four times daily is an alternative 1. It's also important to consider the potential for community-acquired MRSA (CA-MRSA) and adjust the antibiotic choice accordingly, with options including clindamycin, trimethoprim-sulfamethoxazole, or doxycycline 1.

In addition to antibiotic therapy, continued breastfeeding or breast milk expression is recommended to prevent milk stasis and promote healing 1. Warm compresses and analgesics such as ibuprofen 400-600 mg every 6 hours or acetaminophen 650 mg every 6 hours can help manage pain. Patients should be reassessed within 48-72 hours to ensure improvement. If the abscess recurs or fails to resolve, further evaluation for underlying conditions or resistant organisms may be necessary.

Key considerations in the management of breast abscesses include:

• Incision and drainage as the primary treatment
• Antibiotic therapy to cover common breast pathogens
• Consideration of CA-MRSA and adjustment of antibiotic choice
• Continued breastfeeding or breast milk expression to promote healing
• Pain management with warm compresses and analgesics
• Regular follow-up to ensure improvement and address any complications.

From the Research

Treatment for Breast Abscess

The first-line treatment for a breast abscess is a topic of discussion among medical professionals, with various studies suggesting different approaches.

• Needle aspiration, either with or without ultrasound guidance, is recommended as the first-line treatment for breast abscesses 2, 3.
• This approach has potential benefits, including superior cosmesis, shorter healing time, and avoidance of general anesthesia 2.
• Multiple aspiration sessions may be required for cure, and ultrasound-guided percutaneous catheter placement may be considered as an alternative approach for treatment of larger abscesses (>3 cm) 2.
• Surgical incision and drainage should be considered for first-line therapy in large (>5 cm), multiloculated, or long-standing abscesses, or if percutaneous drainage is unsuccessful 2.
• The use of antibiotics is also crucial in the treatment of breast abscesses, with the choice of antibiotic depending on the causative organism and its sensitivity pattern 4, 5.
• Studies have shown that Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA), is a common causative organism in breast abscesses, and empirical antibiotic therapy should be guided by the institutional antibiogram 4, 5.
• Ciprofloxacin with clindamycin has been recommended as initial empirical therapy for breast abscesses 4.
• The Mammotome biopsy system has also been shown to be an effective treatment strategy for breast abscesses, particularly for those with unfavorable outcomes with antibiotic treatment and/or needle aspiration failure 6.
