Lung cancer cases linked to air quality

Potential health impact of smog could be much greater than SARS, expert says

A type of lung cancer reported to be increasing in Beijing has been linked to worsening air quality, with an expert warning that the potential health impact could be much greater than the SARS epidemic in 2003.

"The proportion of lung adenocarcinoma cases is increasing," said Wang Ning, deputy director of the Beijing Office for Cancer Prevention and Control, adding that there has been a drop in the proportion of squamous cell lung cancer cases in the capital.
