text: Following untreated mastitis, breast<unk>  could occur. 
  Breast<unk>  is usually caused by staphylococcus aureus bacterial infection to an injured breast skin. Staphylococcus aureus could form<unk>  by secretion of several killing agents like enzymes and toxins which causes breast tissue necrosis. In a reaction to these bacterial substances, assembled white blood cells in this tissue produces anti-bacterial anti-bodies that help in killing the bacteria. However, these cells cause damage to the soft tissue contributing in the<unk>  formation. 
  As the breast<unk>  is the complicated form of mastitis, the pathophysiology is mostly like the mastitis pathophysiology.
