Studies led by Professor Lennart Hardell in Sweden found significantly increased risk of brain tumors

from 10 or more years of cellphone or cordless phone use.

Among their many

significant findings are the following:

$ For every 100 hours of cellphone use, the risk of brain cancer increases by 5%;

$ For every year of cellphone use, the risk of brain cancer increases by 8%;

$ After 10 or more years of digital cellphone use, there was a 280% increased risk of

brain

cancer

$ For digital cellphone users who were teenagers or younger when they first starting

using a cellphone, there was a 420% increased risk of brain cancer.  

The study's suggestion that the phone be kept one inch from the body has been met with vitriol and ridicule from the tech industry.
