How do you know we shouldn't be worrying about cellphones?
Because most of the controlled studies published in peer-review scientific journals have failed to find an increased risk of cancer with cell phone use. For example:
A large Danish study looked at cohort of 420,095 persons whose first cellular telephone subscription was between 1982 and 1995 and who were followed through 2002 for cancer incidence. Cellular telephone use was not associated with increased risk for brain tumors (Standardized incidence ratio = 0.97), acoustic neuromas (SIR = 0.73), salivary gland tumors (SIR = 0.77), eye tumors (SIR = 0.96), or leukemias (SIR = 1.00). Among long-term subscribers of 10 years or more, cellular telephone use was not associated with increased risk for brain tumors (SIR = 0.66, 95% CI = 0.44 to 0.95), and there was no trend with time since first subscription. There was no evidence for an association between tumor risk and cellular telephone use among either short-term or long-term users. Moreover, the narrow confidence intervals provide evidence that any large association of risk of cancer and cellular telephone use can be excluded. (Schüz J, et al. .Cellular telephone use and cancer risk: update of a nationwide Danish cohort. J Natl Cancer Inst. 2006 Dec 6;98(23):1707-13.)
In a population-based case-control study, the authors identified all cases aged 20-69 years diagnosed with parotid gland tumor during 2000-2002 in Denmark and Sweden. For egular mobile phone use, regardless of duration, the risk estimates for malignant and benign tumors were 0.7 (95% confidence interval: 0.4, 1.3) and 0.9 (95% confidence interval: 0.5, 1.5), respectively. Similar results were found for more than 10 years' duration of mobile phone use. The risk estimate did not increase, regardless of type of phone and amount of use. The authors conclude that the data do not support the hypothesis that mobile phone use is related to an increased risk of parotid gland tumors. (Lönn S, et al. Mobile phone use and risk of parotid gland tumor. Am J Epidemiol. 2006 Oct 1;164(7):637-43. Epub 2006 Jul 3.)
Let me just give you a brief lesson on cancer...
Dang! I wasted all that time taking medical oncology, epidemiology, mechanisms of disease, and pathology when I could have just gotten free lessons here.
