Reuters Health interviewed Dr. Michael Ong, UCLA Fielding School of Public Health professor of health policy and management, about a study that found individuals exposed to secondhand smoke are more likely to develop oral cancers than those who do not have this exposure
People who are exposed to secondhand smoke are more likely to develop oral cancers than their counterparts who don't have this exposure, a systematic review and meta-analysis suggests.
Researchers examined data from five previously published studies with a total of 1,179 cases of oral cancer and 5,798 controls. The analysis included 3,452 people who had exposure to secondhand smoke and 3,525 who didn't.
Overall, individuals with secondhand smoke exposure were significantly more likely to develop oral cancer (odds ratio 1.51), researchers report in Tobacco Control.
