lung cancer patients non-smokers

In what could be an alarming fallout of air pollution, top cancer doctors say they have noted a significant rise in lung cancer among non-smokers in recent years. Roughly one in every five persons diagnosed with the disease does not smoke, they said.

Till about a decade ago, less than 10% of all lung cancer patients were non-smokers. This percentage has now gone up to around 20%, which is significantly high. Rising pollution levels may be playing a role.
