WASHINGTONOverall cancer incidence and mortality have continued
to decline in the United States, but incidences of some cancers
continue to rise, and significant differences in both incidence and
mortality persist among different racial and ethnic groups.
Between 1990 and 1996, the national incidence rate declined an
average of 0.9% per year, and mortality fell 0.6% per year, according
to the Annual Report to the Nation on the Status of Cancer,
1973-1996. The study was prepared by the American Cancer
Society, National Cancer Institute, and the Centers for Disease
Control and Prevention (CDC).
Lung, prostate, breast, and colorectal cancer were the top four
cancer incidence sites among the five populations studiedwhite,
black, Hispanic, American Indian/Alaskan Native, and Asian/Pacific
Islander. The same sites were the top four causes of cancer deaths in
all groups, with one exception. Liver cancer replaced breast cancer
in the mortality top four among Asians and Pacific Islanders.
Although breast cancer incidence has changed little during the 1990s,
breast cancer mortality has declined about 2% per year. Colorectal
cancer incidence and deaths continued to decline among both men and
women. New cases and deaths have continued to rise for
non-Hodgkins lymphoma, although less so in the 1990s than in
the 1980s. And the incidence of melanoma continued to rise about 3%
annually from 1990 to 1996, although mortality has remained constant.
