Lung cancer incidence is higher among African Americans than Caucasians, with the highest rate being among African American males. Lung cancer occurs 50% more frequently in African-American men than in white men. Among women, it is 46, 43 and 20 per 100,000 for African Americans, Caucasians and Hispanics respectively. Lung cancer mortality does not differ between African American and Caucasian women (33 and 34 per 100,000 respectively). However, African American men have the highest mortality rate, 101 per 100,000 versus 70 per 100,000 for Caucasian males. Lung cancer incidence and mortality rates may reflect economic differences rather than biological or smoking differences as a recent study found that Caucasian girls were more likely to smoke on daily basis and African American girls were more likely to have never smoked.
