According to the World Health Organization, environmental pollution of air, water and soil with carcinogenic chemicals accounts for one to four percent of all cancers. Exposure to carcinogens also occurs via the contamination of food by chemicals, such as aflatoxins or dioxins. Indoor air pollution from coal fires doubles the risk of lung cancer, particularly among non-smoking women.
