[00:00.39] It's long been known that giving up cigarettes, reducing alcohol intake and avoiding sunburn can reduce the chances of getting certain types of cancer.

[00:08.90] But this new study suggests that our lifestyle choices could have an impact on between 70% and 90% of all cancer cases.

[00:16.61] The team at Stony Brook University re-analysed existing cancer data and found that random cell mutation rarely gets to the point of causing cancer without some form of external factor like toxic chemicals or radiation.

[00:41.04] The findings are expected to influence medical advice on avoiding the disease.
