Trends in incidence

Between 1975 and 2000, cancer increased in incidence in all age levels below 45 years of age (Fig. 1.11). Most of the increase in incidence in 25- to 44-year-olds occurred in males (Fig. 1.12), in large part due to increases in soft-

tissue sarcoma (notably Kaposi sarcoma), non-Hodgkin lymphoma, and testicular carcinoma (Fig. 1.13). Among females less than 45 years of age, the greatest increases occurred in germ cell tumors (Fig. 1.14).

There is evidence that the increase in incidence has declined among 15- to 29-year-olds, with a leveling off
