This annual report provides the estimated numbers of new cancer cases and deaths in 2017, as well as current cancer incidence, mortality, and survival statistics and information on cancer symptoms, risk factors, early detection, and treatment. In 2017, there will be an estimated 1,688,780 new cancer cases diagnosed and 600,920 cancer deaths in the US.

In 2017, nearly 13% of all cancers diagnosed in adults ages 20 and older will be rare cancers, defined in this report as a cancer with fewer than 6 cases per 100,000 people per year. This year’s special section reviews statistics for 28 rare cancers, including incidence and mortality rates and trends, stage at diagnosis, and survival, and also provides an overview of risk factors and symptoms for select cancers. It is intended to inform anyone interested in learning more about rare cancers in adults, including policy makers, researchers, clinicians, cancer control advocates, patients, and caregivers. (Childhood and adolescent cancers are reviewed in the special section of Cancer Facts & Figures 2014.)
