It’s official now – living may make you ill
Nearly half of cancers diagnosed in the UK each year - over 130,000 in total - are caused by avoidable life choices including smoking, drinking and eating the wrong things, says the Cancer Research UK report. Its authors claim it is the most comprehensive analysis to date on the subject.
Lead author Prof Max Parkin said: "Many people believe cancer is down to fate or 'in the genes' and that it is the luck of the draw whether they get it.”Looking at all the evidence, it's clear that around 40% of all cancers are caused by things we mostly have the power to change."
No mention of the other 60% then...and when has 40% been nearly half? Good old BBC more sensationalist reporting again
