Cellular damage and altered carbohydrate expression in P815 tumor cells induced by direct electric current: an in vitro analysis.

abstract：:In May 2011, the International Agency on Cancer in Research (IARC) issued an official statement concluding that cell phone usage was "possibly carcinogenic to humans." There have been considerable doubts that non-experts and experts alike fully understood what IARC's categorization actually meant, as "possibly carcino...
