OAK BROOK, Ill. - Breast cancer death rates have stopped declining for women in the U.S. younger than age 40, ending a trend that existed from 1987 to 2010, according to a new study in

Breast cancer is the most common non-skin cancer and the second most common cause of cancer deaths in women in the U.S., accounting for 30% of all cancers in women. Although most invasive breast cancers occur in women age 40 years and older, 4% to 5% of cases happen in women younger than 40 years.
