Mobiles and coffee deemed 'unlikely to cause cancer'

Drinking coffee, using mobile phones or having breast implants is unlikely to cause cancer, according to a risk ranking system devised by an Australian cancer specialist to debunk popular myths.

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 University of New South Wales Professor Bernard Stewart lists the risk of cancer from proven and likely, to inferred, unknown or unlikely.
