The rate of new cases of lung cancer decreased from 2005 to 2009 in the United States, according to the Centers for Disease Control and Prevention (CDC).
However, the incidence of the disease did not drop in all states.
Nationally, the rate decreased in both men and women during the study period, but the decrease was more rapid in men.
Specifically, lung cancer incidence rates went down from 87 to 78 cases per 100,000 men, a decrease of 2.6% per year, and from 57 to 54 cases per 100,000 women, a decrease of 1.1% per year.
The differences in lung cancer incidence between men and women widened with increasing age. In the 35 to 44 year age group, men actually had slightly lower rates of lung cancer than women.
The new data were published in the January 10 issue of theMorbidity and Mortality Weekly Report.
The CDC has declared reducing tobacco use a "winnable battle," write the report authors, led by S. Jane Henley, MSPH, from the division of cancer prevention and control at the CDC.
And progress was seen in the new numbers.
For instance, lung cancer incidence decreased more rapidly from 2005 to 2009 in men and women 35 to 44 years of age than in other age groups.
"Although many factors might have contributed to this decline, a study of 44 states showed that strong tobacco control indicators were correlated with lower lung cancer incidence rates among adults age 20–44 years," write the authors.
Hitting young people in the pocketbook might be a good strategy, they suggest. "Younger adults might be more sensitive than older adults to certain interventions like increased tobacco prices," they note.
