While the mortality rate has declined among most population groups over the past thirty years, cancers of the lung and bronchus are still the leading cause of cancer death among both men and women in the United States. According to estimates of the American Cancer Society, approximately 235,760 new cases of lung and bronchus cancer and 131,880 deaths were expected to be reported in the year 2021. The high mortality rate is due largely to the fact that a majority of these cancers are not detected until the disease has reached an advanced stage, when treatment is less effective. Lung cancer became an early focus of the SPORE Program due to the huge burden in terms of morbidity and mortality, and the first three Lung SPOREs were funded in 1992.
