The overarching goal of the CPFP is to provide a strong foundation for scientists and clinicians to train in the field of cancer prevention and control. As part of the program, we offer training toward an M.P.H. degree at an accredited university during the first year, followed by mentored research with investigators at the NCI. Outstanding opportunities for cutting-edge research in the basic, quantitative, social and behavioral sciences, and in clinical cancer prevention have been the hallmarks of the CPFP since its inception in 1987. Furthermore, a partnership between the NCI and FDA provides opportunities for prevention research in drugs, biologics, and medical devices. Other educational opportunities are provided throughout the fellowship to complement the research training, including the NCI Summer Curriculum in Cancer Prevention; the Molecular Prevention Laboratory; the NCI Cancer Prevention and Control Colloquia Series; and the weekly Fellows' Research Meeting. Additional leadership and professional development training opportunities are available with the NCI and elsewhere. These aspects of the program, as well as eligibility requirements, application procedures, selected bibliography of current and former fellows' recent publications, and a glimpse at life in the Washington, D.C. area are described in this catalog.
