Lung cancer rates increasing among nonsmoking Asian American women: study

A California study reveals a decline in lung cancer rates across various groups, except for nonsmoking Asian American women, where rates are increasing by 2% annually. The data: In the study published in the Chest medical journal, researchers found lung cancer incidence rates among Asian American females who have never used tobacco are approximately twice as high compared to their counterparts. Despite the association of lung cancer with smokers, up to 20% of U.S. cases reportedly occur in nonsmokers each year.
