What  Is  Breast  Cancer? 

Cancer is a group of diseases in which cells in the body grow, change, and multiply out of control.  Usually, cancer is named after the body part in which it originated.  Breast Cancer refers to the erratic growth of cells that originate in the breast tissue.  A group of rapidly dividing cells may form a lump or mass of extra cancerous (malignant) or non-cancerous (benign).  Malignant tumors penetrate and destroy healthy body tissues.    Sometimes these groups of cells within a tumor may break away and spread to other parts of the body.
