Management of Lactating Women with Suspected Breast Abscess

Rationale for Aspiration Over Other Options

The National Comprehensive Cancer Network recommends repeated aspiration for lactating women with suspected breast abscess, as it serves dual diagnostic and therapeutic purposes, allowing for cytologic examination of fluid and providing symptom relief, while preserving breast tissue and maintaining breastfeeding capability 1, 2, 3
The distinction between complicated and complex cysts is critical, with complicated cysts containing debris or echoes, and complex cysts having solid components, which suggests a 14-23% malignancy risk, and aspiration is preferred for complicated cysts 1, 2, 4

If bloody fluid is obtained, a tissue marker should be placed and cytologic evaluation performed, with further management depending on cytology results, including possible core needle biopsy or excision, as recommended by the National Comprehensive Cancer Network 1, 2, 3
If a persistent mass is present after aspiration, tissue biopsy via core needle technique is mandated to exclude complex cysts with solid components, as suggested by the National Comprehensive Cancer Network 1, 2, 3

The American College of Obstetricians and Gynecologists and the National Comprehensive Cancer Network emphasize the importance of distinguishing between complicated and complex cysts, and proceeding with aspiration for complicated cysts, while considering tissue biopsy for complex cysts 1, 2, 4, 3

The National Comprehensive Cancer Network advises against confusing complicated cysts with complex cysts, and proceeding directly to surgical intervention without attempting aspiration first in lactating women, as this risks unnecessary breast tissue damage 1, 2, 4, 3

The American College of Radiology recommends that more than 80% of palpable masses in lactating women are benign, and immediate excision would result in significant overtreatment 5, 6
Excisional biopsy is reserved for situations where core needle biopsy shows atypical findings, image-discordant results, or when there is a persistent solid mass after aspiration, as stated by the National Comprehensive Cancer Network 7

The American College of Radiology suggests that delayed imaging evaluation of palpable lesions in lactating women due to concerns about malignancy should be avoided, but also recognizes that most (>80%) will be benign 5, 6
