Lung and Bronchus

illustration of human lungsCancer of the lung and bronchus (hereafter, lung cancer)

is the second most common cancer among both men and women and is the leading
cause of cancer death in both sexes. Among men, age-adjusted lung cancer
incidence rates (per 100,000) range from a low of about 14 among American
Indians to a high of 117 among blacks, an eight-fold difference. Between these
two extremes, rates fall into two groups ranging from 42 to 53 for Hispanics,
Japanese, Chinese, Filipinos, and Koreans and from 71 to 89 for Vietnamese,
whites, Alaska Natives and Hawaiians. The range among women is much narrower,
from a rate of about 15 among Japanese to nearly 51 among Alaska Natives, only a
three-fold difference. Rates for the remaining female populations fall roughly
into two groups with low rates of 16 to 25 for Korean, Filipino, Hispanic and
Chinese women, and rates of 31 to 44 among Vietnamese, white, Hawaiian and black
women. The rates among men are about two to three times greater than the rates
among women in each of the racial/ethnic groups.

In the 30-54 year age group, incidence rates among men are double those among
women in most of the racial/ethnic groups. In white non-Hispanics and white
Hispanics, however incidence rates for women are closer to those for men. This
suggests that smoking cessation and prevention programs may have been especially
successful among white men and/or that such programs have not been as effective
among white women.
