A study conducted of 180,000 non-smokers across the US and Puerto Rico showed that 1,100 of them developed lung cancer and died due to the disease.

Researchers found that the risk of developing lung cancer for every person increased by 15 to 27 percent for every 10 extra units of air-pollution.

About time they looked for other reasons why people contract lung cancer. I wouldn’t rule out that the HPV virus that causes throat cancer may also be responsible for lung cancer.
