Researchers looked at 500 Israelis who had developed the condition and compared their mobile phone usage with 1,300 healthy controls.
Those who had used the phone against one side of the head for several hours a day were 50% more likely to have developed a salivary gland tumour.
The research appeared in The American Journal of Epidemiology.
But Dr Sadetzki stressed one study was not enough to prove a link, and that further research was needed.
However...
LINK...the largest and longest-running investigation ever to be carried out into mobile phone usage found no increased risk of any sort of cancer.
...20,000 people in Denmark, some of whom had been using a mobile phone for as long as ten years.
There was in fact a lower incidence of cancer than expected in a group of that size, suggesting mobile phones had no impact on the development of tumours.
Ed Yong, of Cancer Research UK, said: "Mobile phones are a relatively recent invention and new research into any possible health risks is welcome.
"However, it's important to remember that the vast majority of studies so far have found that mobile phones do not increase the risk of any type of cancer."
"further research was needed."
Can anybody say "CASH"?
