There are 36,000 deaths from lung cancer and 46,400 new cases each year, according to research
The number of lung cancer cases among non-smokers has doubled in the last 10 years, with health experts blaming air pollution for the rise.
Previously, nine in ten cases of the disease were linked to cigarette use, but this proportion has decreased.
National data regarding lung cancer among non-smokers is hard to obtain, so other researchers are yet to notice the trend.
However, a similar trend has been observed in America.
Currently, there are 36,000 deaths from lung cancer and 46,400 new cases each year.
