Breast Abscesses are a complication of mastitis, and a pyogenic abscess can evolve from acute bacterial mastitis.It is frequently observed in non-puerperal mastitis and can be a particularly difficult condition due to the intense discomfort and tendency for recurrence. Breast abscesses require a surgical incision to allow drainage for the abscess,and is usually performed under general anesthesia.

Causes of breast abscesses

A breast abscess can form if you have a breast infection (called mastitis) and it's not treated quickly.
Mastitis most often affects breastfeeding women. It can also happen in women who aren't breastfeeding, but this is less common.
Getting treatment for mastitis as soon as possible can help reduce the risk of getting an abscess.

Treatment in hospital

You'll have an ultrasound scan of your breast to check for an abscess.
The pus can be drained from an abscess with either:

A needle – this might need to be done a few times, and you may have to go back to hospital each time
A small cut in your skin

Your skin will be numbed before this is done. You can usually go home the same day and may be given antibiotics to take at home.
The abscess should heal completely in a few days or weeks.
