Mobile Phone Use and the Risk for Malignant Brain Tumors: A Case-Control Study on Deceased Cases and Controls.

Department of Oncology, University Hospital, Orebro, Sweden.


We investigated the use of mobile or cordless phones and the risk for malignant brain tumors in a group of deceased cases. Most previous studies have either left out deceased cases of brain tumors or matched them to living controls and therefore a study matching deceased cases to deceased controls is warranted. Recall error is one issue since it has been claimed that increased risks reported in some studies could be due to cases blaming mobile phones as a cause of the disease. This should be of less importance for deceased cases and if cancer controls are used. In this study brain tumor cases aged 20-80 years diagnosed during 1997-2003 that had died before inclusion in our previous studies on the same topic were included. Two control groups were used: one with controls that had died from another type of cancer than brain tumor and one with controls that had died from other diseases. Exposure was assessed by a questionnaire sent to the next-of-kin for both cases and controls. Replies were obtained for 346 (75%) cases, 343 (74%) cancer controls and 276 (60%) controls with other diseases. Use of mobile phones gave an increased risk, highest in the >10 years' latency group yielding odds ratio (OR) = 2.4, and 95% confidence interval (CI) = 1.4-4.1. The risk increased with cumulative number of lifetime hours for use, and was highest in the >2,000 h group (OR = 3.4, 95% CI = 1.6-7.1). No clear association was found for use of cordless phones, although OR = 1.7, 95% CI = 0.8-3.4 was found in the group with >2,000 h of cumulative use. This investigation confirmed our previous results of an association between mobile phone use and malignant brain tumors. Copyright © 2010 S. Karger AG, Basel.

This is interesting.
In the olden days back-of-the-envelope calculations were done to show that power lines can not cause cancer. The basic touch stone was energy - is there enough energy absorbed to cause heating damage.

Clearly - damage to the chromosomes doesn't always work by heating and, at least a decade ago, research started to make that clear.

Cell phones have been changing a lot. In the olden days (a few years ago) a phone basically operated at full power all of the time. But that has changed as the need to conserve battery power and reduce noise and driven the technology to adapt. Newer cell phones reduce their power to what is enough. Clearly this will reduce the cases of cancer.

Also - when/if research can identify the actual mechanism of cancer formation then it would be possible to adjust the frequency / power to eliminate (minimize) the problem.

Myself I've never used a cell phone and don't even know how to turn one on. Maybe in a decade or so my kids will decide to get one; but I have no need or desire.

I suggest reading Better Off by Eric Brende or anything to do with Voluntary Simplicity. We should make the adoption of new technology a voluntary thought out decision - not just an emotional quick acquisition. From the book Future Shock - how will technology change our society and inter-personal relationships? Do we want that? Is it a good thing? Does it enhance life or suck people into solitude with an illusion of community?
