Here we go with cellphone tumors again

We performed two case–control studies on brain tumours diagnosed during 1 January 1997 to 30 June 2000 and 1 July 2000 to 31 December 2003, respectively. Living cases and controls aged 20–80 years were included. An additional study was performed on deceased cases with a malignant brain tumour using deceased controls. Pooled results for glioma yielded for ipsilateral use of mobile phone odds ratio (OR) = 2.9, 95% confidence interval (CI) = 1.8–4.7 in the >10 years latency group. The corresponding result for cordless phone was OR = 3.8, 95% CI = 1.8–8.1. OR increased statistically significant for cumulative use of wireless phones per 100 h and per year of latency. For high-grade glioma ipsilateral use of mobile phone gave OR = 3.9, 95% CI = 2.3–6.6 and cordless phone OR = 5.5, 95% CI = 2.3–13 in the >10 years latency group. Heredity for brain tumour gave OR = 3.4, 95% CI = 2.1–5.5 for glioma. There was no interaction with use of wireless phones. X-ray investigation of the head gave overall OR = 1.3, 95% CI = 1.1–1.7 for glioma without interaction with use of wireless phones or heredity. In conclusion use of mobile and cordless phone increased the risk for glioma with highest OR for ipsilateral use, latency >10 years and third tertile of cumulative use in hours. In total, the risk was highest in the age group <20 years for first use of a wireless phone.

Does a medical or statistics professional who understands all this jargon want to lay it out for me?

I assume since most people are right handed, these are right side tumors?

I think right handed people mostly hold their cell phones in their LEFT hands to keep their right hand free for actually DOING something.

Not me. Mostly right hand. If I'm doing something, it sits on my desk in speaker mode.

That brings to mind a question. My kids both have "cell phones", and I say "cell phones" because they use them 95% of the time to "text" and when they are actually using a phone as a phone, it's on speaker. I wonder if the studies factor in cell phone use that is texting or on speaker (not up to the ear), e.g. my kids?

The link wasn't usable for me. However, given the large general population use of wireless devices, I'm not sure how they identify cell phone induced tumor vs. any other. Here's another link to comparable article that seems consistent with yours http://www.cancermonthly.com/blog/20...ellphones.html I assume since most people are right handed, these are right side tumors?

Here's another article that researches and discusses glioma location and possible reasons http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1907421/

Personally I tend to send anywhere between 5-20 texts on an average day but can go days without receiving or sending a call and most of the time those calls are for a couple of minutes.
