Breast cancer is the second most common cancer in American women and accounts for 19% of all cancer deaths. The National Cancer Institute estimates that one in eight women will develop breast cancer by the age of 85.
Breast cancer, like the majority of adult cancers, most often occurs in the sixth and seventh decades of life and is predominantly the result of acquired mutations brought about by years of cellular stress and injury. The transformation to cancer is slow, taking years or decades as gene after gene is mutated until one day the mutations are extensive enough to meet the criteria that define cancer.
Symptoms of breast cancer include a thickening or lump in the breast that may or may not be sore, and a change in the shape or weight of the breast including nipple deviation, retraction, or discharge. Skin changes that need to be evaluated include discoloration, scaling, or puckering of the skin that gives an orange peel appearance.
