Breast Cancer Fact Sheet - October 2017
About 1 in 8 U.S. women will develop invasive breast cancer over the course of her lifetime. In 2017, an estimated 255,180 new cases of invasive breast cancer are expected to be diagnosed in men and women, along with 63,410 new cases of non-invasive breast cancer (also known as carcinoma in situ). About 40,610 women are expected to die in 2017 from breast cancer, though there has been a decrease in death rates since 1989, with larger decreases in women under 50. These decreases are thought to be the result of treatment advancements, earlier detection through screening, and increased awareness.
Except for skin cancer, breast cancer is the most commonly diagnosed cancer among American women. As of March 2017, there were about 3.1 million women with a history of breast cancer in the U.S. This figure includes women currently being treated and women who have finished treatment.
