A new risk assessment tool suggests that deodorants, coffee and artificial sweeteners may not be linked to cancer. The tool has been developed through the Cancer Control Program at South Eastern Sydney & Illawarra Health (SESIH) by UNSW researcher, Professor Bernard Stewart.
“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 and drinking coffee or fluoridated water – or at risk bands in between,” said Professor Stewart.
“The media are filled with reports about possible causes of cancer: most commonly, a new and unexpected exposure to a previously suspected carcinogen.”
“It’s one thing to know that arsenic is carcinogenic – but quite another to distinguish between different methods of exposure. That’s what this approach achieves,” said Professor Stewart. “For instance, smelter workers who are exposed to arsenic emissions are much more likely to develop cancer than children who have played on climbing frames constructed from arsenic-treated timber – but the carcinogen is the same.”
Until now there have only been mathematical risk assessments, which are complicated and of a limited application.
“Our approach can be used whenever carcinogenic risk can be implied,” said Professor Stewart.
In an issue of the journal Mutation Research Reviews, the newly developed procedure has been applied to more than than 60 situations, ranging from active smoking to electromagnetic fields in the workplace – which are all deemed to offer some degree of carcinogenic risk. Consequently, each situation can be located within one of five bands corresponding to proven, likely, inferred, unknown or unlikely risk of carcinogenic outcome.
Surveys suggest that tobacco smoking is correctly identified as the major cause of cancer, but a host of other situations – using a mobile phone, air pollution, exposure to DDT, eating dioxin-contaminated fish, using hair dyes, and drinking alcoholic beverages – are often given similar risk status.
“We now have a means of indicating which carcinogenic risks are comparable by reference to the type of evidence available,” says Professor Stewart. “This risk assessment gives the lie to the attitude that ‘everything causes cancer’.”
