NEW YORK (Reuters Health) - Smokers, especially those over the age of 60, are more than twice as likely as nonsmokers to develop a specific type of acute myeloid leukemia (AML), study findings suggest. While smoking has long been thought to be a possible risk factor for AML--the most common type of leukemia diagnosed in adults--the research results have been contradictory. The results of a new study suggest that smoking may contribute to some types of the leukemia, but not others, helping to explain the murky results.
