Breast cancer affects 1 in 8 women during their lives, and many of us know someone — a mother, sister, friend — who has had it. It is the second-leading cancer killer of women in the United States, next to lung cancer. Thanks to screening, breast cancer often can be found early, when the chance of successful treatment is best. In fact, many women are even cured of the disease.
