Breast Infection: Causes and Treatments

The breast is made up of tissue and fat that surround glands and ducts that lead to the areola and the nipple. The ducts that carry milk start at the nipple and extend into the underlying breast tissue, similar to the spokes of a wheel. The lactiferous ducts are under the areola and they fill with milk during lactation after a woman gives birth. When a girl reaches puberty, hormonal changes cause the ducts to grow and fat deposits in the breast tissue to increase. However, sometimes a female's breast tissues get infected. How does this happen and what can you do to deal with this problem?
