Efforts are needed to improve screening for colorectal cancer within these groups. As is the case for other cancer sites, prevalent cases of colorectal cancer are more likely than incident cases to be aged 65 and older (76.7 versus 68.1 percent) (Figure 2-28). Hodgkin’s DiseaseIn 2005, there will be about 7,350 new cases of Hodgkin’s disease and 1,410 HD deaths in the United States. Epidemiologic evidence suggests that HD results from a complex of related conditions that are in part mediated by infectious diseases, immune deficits, and genetic susceptibilities (Cartwright and Watkins, 2004). Death rates have fallen more than 60 percent since the early 1970s because of better diagnosis and treatment. There are no recommended screening tests for HD. Improvements in treatment have increased the size of the survivorship population, estimated at 145,501 in 2002. HD is an unusual cancer in that as many as 64 percent of new cases of HD and 60 percent of survivors of HD are under age 45 (Figure 2-29).
