Sometimes the normal fat cells in the breast become round, firm lumps
made up of damaged fatty tissue. This is called fat necrosis of the breast. The
lumps may or may not be painful. This problem is most often seen in obese women
who have very large breasts or after an injury to a breast.
Fat necrosis can be caused by an injury or blow to the breast.
Sometimes the skin around this lump looks red or bruised. Fat necrosis is
sometimes seen following a motor vehicle accident in which the seat belt has
forcefully squeezed the breast.
