Men who work in certain occupations continue to be at increased risk of lung cancer, new research from Italy shows.

In fact, about 5 percent of lung cancers in men are job-related, Dario Consonni of the IRCCS Ospedale Maggiore Policlinico in Milan and associates found.

While cigarettes are by far the most important cause of lung cancer, chemicals and other on-the-job hazards “play a remarkable role” in lung cancer risk, the researchers write in the American Journal of Epidemiology.

To provide updated information on these risks, they looked at the association between lung cancer and jobs either known or suspected to increase the risk of the disease in 2,100 people diagnosed with lung cancer and 2,120 healthy individuals matched by age, gender and residence.
