Action To Tackle Air Pollution Failing To Keep Up With Research 26

Globally, outdoor air pollution is second only to tobacco as greatest cause of lung and respiratory cancers. From a report: This year marks a decade since the International Agency for Research on Cancer (IARC) gathered in Lyon, France, to unanimously declare that air pollution caused cancer in humans. Air pollution was classified as a type 1 carcinogen, the most certain category possible. This was mainly based on more than 20 years of research in particle pollution and lung cancer. The number of research studies has almost doubled since the IARC meeting in Lyon, with even more evidence on lung cancer in never-smokers, but governmental action to reduce air pollution has not kept up.

Globally, outdoor air pollution is second only to tobacco as the greatest cause of lung and respiratory cancers. This holds true in almost all parts of the world, with a notable exception of low-income countries where people (especially women and children) also breathe smoke in their homes from cooking on open fires. In the past 10 years new studies have linked air pollution to other cancers, including breast and bladder cancer. These have also been associated with nitrogen dioxide, a pollutant from diesel traffic that is being targeted by low emissions zones in many cities. There is emerging evidence of links to childhood leukaemia too. For those people with lung cancer, smokers and never-smokers, their prognosis and survival appears to be reduced if they live in a polluted area. Research includes a recent study of more than a quarter of a million people with lung cancer in Pennsylvania. This raises questions about the impact of air pollution on the way that cancer progresses and how it may change the effectiveness of chemotherapy.
