Current evidence on breast cancer among US Hispanic women indicates a significant public health threat, although few studies have assessed the heterogeneity in breast cancer risk among Hispanics of different origin. ⋯ The current findings indicate that Hispanic women have a significantly lower risk of breast cancer compared with NHW women, although the risk according to BCRAT differed significantly between specific Hispanic subgroups. We provide estimates of the number of US Hispanic women from six subgroups who may be eligible for prophylactic breast cancer chemoprevention. The authors concluded that future studies should further investigate the heterogeneity in breast cancer risk and risk factors between Hispanic women of different origins.

The National Lung Screening Trial (NLST), which was conducted between 2002 and 2009, demonstrated that screening with low-dose computed tomography (LDCT) reduced lung cancer mortality by 20% among screening-eligible populations compared with chest x-ray. In this article, the authors provide an estimate of the annual number of lung cancer deaths that can be averted by screening, assuming the screening regimens adopted in the NLST are fully implemented in the United States. ⋯ The data from the current study indicate that LDCT screening could potentially avert approximately 12,000 lung cancer deaths per year in the United States. Further studies are needed to estimate the number of avertable lung cancer deaths and the cost-effectiveness of LDCT screening under different scenarios of risk, various screening frequencies, and various screening uptake rates.
