Many factors contribute to changes in cancer incidence, including changes in risk exposures or changes in the use of cancer screening tests (1).To monitor changes in cancer incidence and assess progress toward achieving Healthy People 2020 objectives,* CDC analyzed data from U.S. Cancer Statistics (USCS) for 2012, the most recent data available.USCS includes high quality incidence data from CDC's National Program of Cancer Registries (NPCR) and the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program, survival data from NPCR, and mortality data from the National Vital Statistics System (2).In 2012, a total of 1,529,078 invasive cancers were reported to cancer registries in the United States (excluding Nevada), for an annual incidence rate of 440 cases per 100,000 persons.Cancer incidence rates were higher among males (483) than females (412), highest among blacks (446), and ranged by state, from 371 to 515 per 100,000 persons (355 in Puerto Rico).The proportion of persons with cancer who survived ≥5 years after diagnosis was 66%.The proportion was the same for males and females (66%) but lower among blacks (60%) compared with whites (66%).These cancer incidence, survival, and mortality surveillance data are continually tracked and used by states to effectively plan health care allocation and support services.Invasive cancers are all cancers excluding in situ cancers (except in the urinary bladder) and basal and squamous cell skin cancers.Data on new cases of invasive cancer diagnosed in 2012 (the most recent year available) were obtained from population-based cancer registries affiliated with NPCR and SEER programs in each state, the District of Columbia (DC), and Puerto Rico (2).For comparability with past estimates, data for the United States were restricted to the states and DC, and data for Puerto Rico were analyzed separately.Data from DC and all states except Nevada met USCS publication criteria for 2012 † ; consequently, incidence data in this report cover 99% of the U.S. population.Cases were first classified by anatomic site using the International Classification of Diseases for Oncology, Third Edition.§ Cases with hematopoietic histologies were further classified using the World Health Organization Classification of Tumours of Haematopoietic and Lymphoid Tissues, Fourth Edition.¶ Breast cancers were characterized by stage at diagnosis using SEER Summary Staging Manual 2000**; late-stage cancers included those diagnosed after they had spread regionally or metastasized.
