No real surprise when taking into consideration the pollution in many of the cities in the country.
Quote:
The number of lung cancer cases in the Chinese capital Beijing has soared over the last decade.
According to figures published by the state-run Xinhua news agency, they have increased by more than 50%.
Beijing health officials say smoking is still the number one cause of lung cancer, but they admit air pollution is also a factor.
The World Health Organization (WHO) recently estimated that polluted air kills millions of people every year.
