Breast cancer is the second leading cause of cancer deaths among women in developed countries.[1] It is estimated that about 12 percent of women in the United States will develop invasive breast cancer over the course of their lifetime and more than 200,000 new cases of invasive breast cancer are expected to be diagnosed in 2015.[2] It is important to know the risks and warning signs of breast cancer, and having the benefit of early detection is invaluable, but sometimes that’s easier said than done.
