According to one recent article, Dr. Devra Davis, president of the Environmental Health Trust stated, "Financial threats from litigation are growing in step with scientific evidence linking phones to health damages."
Companies including Blackberry, EE, Nokia and Vodafone have told investors they could face legal action from device users if research eventually finds links between their products and cancer.
British Telecom, which owns EE, tells investors starkly in its 2017 annual report: "We can't provide absolute assurance that research in the future won't establish links between radio frequency emissions and health risks."
And Nokia says: "There have been some research results that indicated the possibility that electromagnetic waves emitted from mobile devices and base stations have adverse health effects, such as increasing the risk of cancer."
The news comes after we revealed brain cancer patient Neil Whitfield, 60, is the first Briton to sue a phone maker and could win up to £1million from Nokia if successful.
The firms involved say they have a duty to warn shareholders of any risk, however unlikely.
A court in Italy recently ruled a link between tumours and mobiles and the International Agency for Research into Cancer says they are a "possible carcinogenic."
And in France, Orange has recalled around 90,000 Hapi 30 phones because of the device's radiation level.
(Dr. Devra Davis said) "Further still, the Italian court decision indicates any firm that requires mobile use as a condition of work faces major liability."
Blackberry and Nokia warn shareholders of possible legal action in reports to the US Securities and Exchange Commission.
Nokia says despite adhering to regulations "concerns over the adverse effects on health... could make it difficult to acquire and retain customers.
Vodafone says there is "no evidence" of harm but adds: "A change to this view could result in impacts." Blackberry says "perceived risks" could affects sales and lead to legal battles.
Mr Whitfield blames Nokia phones for giving him an acoustic neuroma on a nerve between his inner ear and brain. "Phone companies don't give a jot about health."
Vodaphone is WRONG to claim there is "no evidence" of harm.
Mr. Whitfield though seems to be right on the money - "phone companies don't give a jot about health."
