Evaluating Progress in Radon Control Activities for Lung Cancer Prevention in National Comprehensive Cancer Control Program Plans, 2011-2015.

Radon is the second leading cause of lung cancer among smokers and the leading cause among nonsmokers. The Centers for Disease Control and Prevention's National Comprehensive Cancer Control Program (NCCCP) funds every state, seven tribes, seven territories and the District of Columbia to develop formal cancer plans that focus efforts in cancer control. A 2010 review of cancer plans identified radon-related activities in 27 (42%) plans. Since then, 37 coalitions have updated their plans with new or revised cancer control objectives. There has also been recent efforts to increase awareness about radon among cancer coalitions. This study assesses NCCCP grantees current radon activities and changes since the 2010 review. We reviewed all 65 NCCCP grantee cancer plans created from 2005 to 2015 for radon related search terms and categorized plans by radon activities. The program's most recent annual progress report to CDC was also reviewed. We then compared the results from the updated plans with the findings from the 2010 review to assess changes in radon activities among cancer coalitions. Changes in state radon laws between 2010 and 2015 were also assessed. While a number of cancer plans have added or expanded radon-specific activities since 2010, approximately one-third of NCCCP grantees still do not include radon in their cancer plans. Cancer programs can consider addressing radon through partnership with existing radon control programs to further reduce the risk of lung cancer, especially among non-smokers.
