Hardell Group Reaffirms Wireless Phone Tumor Risks

But Not for Meningioma

Using a new data set covering 2007-2009, Lennart Hardell and his research team have reaffirmed their previous findings that long-term use of a wireless phone leads to higher rates of both malignant brain tumors and acoustic neuromas (AN), but not of meningiomas, a type of benign brain tumor. In general, they report, the longer the use, the greater the risk for AN and malignant brain tumors.

All three new papers are open access. For the malignant brain tumor paper, click here; for the AN paper, click here, and for the meningioma paper, click here.

An excerpt from the brain tumor paper:

“In summary, our results are consistent with an early effect in carcinogenesis (initiator) by analogue mobile phones, and both an early (initiator) and late (promoter) effect by wireless phones of the digital type.”

One from the acoustic neuroma paper:

“The risk increased with time since first use. For use of both mobile and cordless phones the risk was highest in the longest latency group. Tumor volume increased per 100 h of cumulative use and years of latency for wireless phones.”

And one from the meningioma paper: 

“The present results strengthen our previous findings of an increased risk for glioma and acoustic neuroma, since a systematic bias in those studies would have been expected also in this study of meningioma using the same methodology. An indication of increased risk for meningioma was seen in the group with highest cumulative use but was not supported by statistically significant increasing risk with latency.”
