How air pollution is changing our view of cancer

According to the World Health Organisation, air pollution causes 7
million premature deaths every year. We’ve known for a long time
that air pollution causes lots of health problems, including lung
cancer – but exactly how the two were linked was somewhat of
mystery. Last week, a team from the Francis Crick Institute and
University College London presented findings that shed new light on
the role between air pollution and lung cancer. And, in doing so,
could make us rethink how cancer develops. Madeleine Finlay speaks
to the Guardian’s science correspondent Hannah Devlin about how
scientists uncovered this link – and what it might mean for the
future of the field.. Help support our independent journalism at
