WEDNESDAY, Nov. 10 (HealthDay News) -- Whites and blacks in the
United States are much more likely to develop lung cancer than
other racial/ethnic groups, a new federal study finds.
Researchers analyzed 1998 to 2006 data from 38 states and the
District of Columbia. They found that the annual incidence of lung
cancer per 100,000 people was 76.1 for blacks, 69.7 for whites,
48.4 for American Indians/Alaska Natives (AI/ANs), 38.4 for
Asian/Pacific Islanders, and 37.3 for Hispanics.
People ages 70 to 79 had the highest incidence of lung cancer at
about 463 cases per 100,000. Incidence was highest in the South (76
percent) and lowest in the West (about 59 percent), the study
Among whites, the highest incidence of lung cancer was in the
South (76.3). The highest rates among blacks (88.9), AI/ANs (64.2)
and Hispanics (40.6) were in the Midwest. The highest rates among
Asian Pacific Islanders was in the West (42.5).
The variations may be due to regional differences in smoking
prevalence, exposure to cancer-causing substances, and other
factors, according to the study.
"These findings identify the racial/ethnic populations and geographic regions that would most benefit from enhanced efforts in primary prevention, specifically by reducing tobacco use and exposure to environmental carcinogens," the researchers wrote.
The study appears in the Nov. 12 issue of the
Morbidity and Mortality Weekly Report, published by the U.S. Centers for Disease Control and Prevention.
Lung cancer is the second most common cancer and the leading
cause of cancer death in the country, according to the CDC.
