Mastitis with Breast Abscess: Managing the Discrete Tender Lump

This protocol covers mastitis complicated by a breast abscess — a localised collection within breast tissue that presents as a discrete, tender lump in the breast. The lump may feel tense or fluctuant on examination, distinguishing this presentation from uncomplicated mastitis.

A breast abscess is a localised collection in the breast tissue resulting in a painful breast lump. It is potentially secondary to bacterial mastitis that is rapidly progressive or not managed expeditiously. Beyond the systemic signs of mastitis, the hallmark finding is a discrete tender lump — which may be tense or fluctuant — requiring targeted management.

The aim is for inflammation of the breast to settle within 24–48 hours of initiating management, with review scheduled to confirm response.

Where specialist resources are available, the first-line approach involves a procedure to drain the abscess collection alongside antibiotic cover. The choice of antibiotic is guided by microbiological findings. The complete regimen — including the full sequence of steps and additional management — is detailed in the structured protocol.
