Answer

Whereas lung cancer incidence rates are similar among African-American and white women, lung cancer occurrence is approximately 45% higher in African-American men than in white men. [22] This increased incidence has been attributed to differences in smoking habits; however, recent evidence suggests a slight difference in susceptibility.

From 1995-2001, the 5-year relative survival rate was 13% lower in African Americans compared with white individuals. [22] This racial gap persisted within each stage at diagnosis for both men and women.

Trends in 5-year survival rates in lung cancer from 1975-2003 revealed that while modest gains occurred in 5-year survival rates among whites, survival rates remained unchanged in the African-American population. Current 5-year survival rates are estimated to be 16% among whites and 13% among non-whites.
