A growing literature documents persistent disparities by socioeconomic position (SEP) and race/ethnicity across the cancer control continuum, with higher risk and worse outcomes observed for lower socioeconomic groups and those representing some ethnic/racial minorities (Institute of Medicine 1999, Lantz et al. 1998, Levy et al. 2006, Schwartz et al. 2003, Sorensen et al. 1995). These disparities are evident for cancer risk-related behaviors, including tobacco use, diet, and physical activity; risk factors such as overweight and obesity; cancer screening for early detection; diagnosis and treatment; and quality of life associated with survivorship and treatment at the end of life (Christian et al. 2006, Institute of Medicine 1999, 2003, Sequist and Schneider 2006); as well as for morbidity and mortality rates (Bouchardy et al. 2002, Melchior et al. 2007, Menvielle et al.
