    SH......this is a secret study.
no press release. Let's keep quiet about it, so none will know.
Have you heard about the new study of the Interphone from 5 countries? it found an increased risk for brain tumors at the same side of  the brain where the the mobile phone was used more than 10 years (on the basis of 77 cases and 117 controls).  Have you read in the news that prof Hardell says that these results  actually confirm his findings?  
Have you read in the news that when the authors write in the abstract, "We found no evidence of increased risk of glioma related to regular mobile phone use", by "regular" they mean on average once a week during at least 6 months. The regular users definition is a dirty trick, they can include people who use the phone rarely and bias/ dilute the risk  findings.  
If you haven't heard all this, you are not alone.  There was simply no press release.  But you probably couldn't get away of all the press items on the Danish study that denied a link  yet did not reveal it was industry funded that was white-washed through the Danish association"against" cancer.

Mobile phone use and risk of glioma in 5 North European countries.

STUK, Radiation and Nuclear Safety Authority, Helsinki, Finland.

Public concern has been expressed about the possible adverse health effects of mobile telephones, mainly related to intracranial tumors. We conducted a population-based case-control study to investigate the relationship between mobile phone use and risk of glioma among 1,522 glioma patients and 3,301 controls. We found no evidence of increased risk of glioma related to regular mobile phone use (odds ratio, OR = 0.78, 95% confidence interval, CI: 0.68, 0.91). No significant association was found across categories with duration of use, years since first use, cumulative number of calls or cumulative hours of use. When the linear trend was examined, the OR for cumulative hours of mobile phone use was 1.006 (1.002, 1.010) per 100 hr, but no such relationship was found for the years of use or the number of calls. We found no increased risks when analogue and digital phones were analyzed separately. For more than 10 years of mobile phone use reported on the side of the head where the tumor was located, an increased OR of borderline statistical significance (OR = 1.39, 95% CI 1.01, 1.92, p trend 0.04) was found, whereas similar use on the opposite side of the head resulted in an OR of 0.98 (95% CI 0.71, 1.37). Although our results overall do not indicate an increased risk of glioma in relation to mobile phone use, the possible risk in the most heavily exposed part of the brain with long-term use needs to be explored further before firm conclusions can be drawn.
