Editor's note: We've published a series of photographs of nurses at work on our cover in recent years. They were taken from photojournalism contests we held in 2005 and 2007 after seeing too many images of nurses at work that were trite, uninteresting, and failed to reflect the nurses' daily challenges.

We're committed to showing nurses on the cover, and we also want to highlight broader health and health care issues. Breast cancer is one of the leading killers of women, including nurses, and we chose Nursing Bra because it is charming and whimsical and was created for a very good purpose.
