There is a causal relationship. It hasn't been 100% proven that cell phones are the culprit.
And certainly, what accounts for all the prostate cancer historically, before that dark day when cellphones flooded the market.
@ Joe Blogs-no, dude, I meant "causal" relationship, not "casual." The causality is akin to not cutting back on cholesterol and ultimately dying of coronary blockage. The cholesterol was not THE ONLY FACTOR in the lethal cardio event: veins were blocked, the brain reduced in its 02 delivery, aging, medication, misdiagnosis, genes..... all too, play a CAUSAL role, but are not 100% responsible for the end product.
Listen, when we were kids, we knew not to mess with a doctors X-ray machine, because even in the 1950s, common sense told people that X-rays were a mixed blessing at best. At one point, and I'm not making this up, shoe stores used to X-ray a customer's foot (at least here in the US) with the new shoe on to see if it fit. I noticed they don't do that anymore.
Surely having a cellphone connected to your ear at every possibility isn't any more healthy than indiscriminate x-rays.
