NACDD is collaborating with the Division of Cancer Prevention and Control at CDC to convene a meeting of interdisciplinary experts to discuss the state of the evidence for cancer risk-related factors during early adulthood. This project is focused on primary cancer prevention, examining cancer risk factors relevant to early adulthood (18-44) as they may influence the development of cancer later in life. Many of the risk factors are expected to be unrelated to medical care. This is a continuation of work underway by the CDC Cancer Prevention Across the Lifespan Workgroup, which has already convened meetings of experts to discuss cancer prevention during pre-adolescence/adolescence and midlife. In addition to the invitation-only meeting scheduled for April 13-14, 2016, NACDD is conducting a literature search and will collaborate with the CDC to submit a paper to appropriate public health journals. Results of previous meetings are published in the Journal of Adolescent Health and the Journal of Preventive Medicine.
