The cancer risk assessment reaffirms smoking, alcohol, and exposure to sunlight as leading risk factors, but allays concerns about coffee, mobile phones, deodorants, breast implants, and water with added fluoride.
The five-point system created by Bernard Stewart, a University of New South Wales professor, lists the risk of cancer from proven and likely to inferred, unknown, or unlikely.
"Our tool will help establish if the level of risk is high, say on a par with smoking, or unlikely such as using deodorants, artificial sweeteners, drinking coffee," Stewart said.
He found active smokers and ex-smokers to be the most at risk, although the risk is reduced for people who quit smoking.
Drinking alcohol was also a high risk factor, particularly for people who also smoke, although Stewart said no specific type of alcoholic drink was most strongly to blame.
Drinking chlorinated water and using a mobile phone was far less likely to cause cancer, Stewart said, although the
He said there little risk from coffee, deodorants, fluoridated water, breast implants, or dental fillings.
Stewart's research was published in the latest edition of the Mutation Research Reviews journal to mark World Cancer Day on Monday.
