A top (?) cancer researcher suggests that cell phone use is more dangerous than cigarettes, as it may double the risk of brain cancer. Having relatives who've died of lung cancer, and not having relatives who've died of brain cancer, I was skeptical.
Turns out my skepticism was justified. Only about 13000 people die each year in our country from brain cancers and tumors, and over 160,000 people die each year from lung cancer--and this doesn't even count smoking-related deaths from emphysema, heart disease, and so on.
Plus, the relative risk for cell phones is 2.0 or less--generally in the "statistically insigificant" category. For smoking, it's about 40--clearly statistically significant.
I do believe that medical journals used to do a process called "peer review" to figure out "subtle" problems with methodology like this. Evidently that's no longer the case.
