American Cancer Society Denim Day is Otober 6, 2017. Please join us again to help support the fight against breast cancer. This year about 252,710 American women are expected to be diagnosed with breast cancer, while 40,610 women are expected to die from the disease. With deaths from the disease among women ranking second only to lung cancer in the United States, we must continue to make progress. The American Cancer Society issues breast cancer screening guidelines, funds research for improved screening and treatment, encourages healthy lifestyles that can help prevent a diagnosis, and provides programs and services for all who face the disease.
