Air Pollution a Leading Cause of Cancer
The United Nation's World Health Organization (WHO) has classified air pollution as a prime cause of cancer worldwide, especially in the case of lung cancer.
The WHO's International Agency for Research on Cancer (IARC) has now placed dirty air in the same category of carcinogens as tobacco smoke, ultraviolet (UV) radiation and plutonium, BBC News reported.
According to IARC, about 223,000 lung cancer deaths globally can be blamed on exposure to air pollution. The majority of these deaths are occurring in rapidly industrializing Asian nations such as China.
