Are Today's Carriers and Handset OEMs Tomorrow's Tobacco Companies?

I was having a conversation with a friend at lunch about the potential connection between mobile phone use and cancer. He said that an attorney "insider" had indicated to him that there was reason to believe there was a link between mobile phone radiation exposure and cancer. Some medical studies have sounded this alarm. Other studies have argued that there is no definitive evidence of a link between mobile phone radiation and brain tumors:

Interphone, an international collaboration, and the largest study of its kind to date, reported that overall, cell phone users have no increased risk of two of the most common forms of brain cancer -- glioma and meningioma. Furthermore, there was no evidence of risk with progressively increasing number of calls, longer call time, or time since the start of the use of cell phones.  However, for the small proportion of study participants who used cell phones the most – measured as cumulative call time over their lifetime – there was a suggestion of increased risk of glioma, though the authors call this finding inconclusive  . . .

For years the Tobacco industry argued that there was no definitive link between smoking and cancer and diluted the evidence with industry funded research that argued the smoking-cancer connection was unproven and/or inconclusive. 

I'm not trying to suggest by implication that there's any similar conspiracy here among wireless industry stakeholders. However mobile phone carriers and OEMs have an interest in a "no cancer" outcome. But I just wonder if 15 years from now we'll have a range of class action lawsuits against those same companies that resemble the tobacco or asbestos litigation of the 1980s?
