Does the usage of cell phones cause brain cancer? It's a debate that has raged for many years around the world. A major study is hoping to answer some of those questions.
A National Institutes of Health study released on Thursday warns that cell phone radiation can cause cancers of the heart, brain and adrenal glands.
But the results of the study do need proper context. The tests for the study were done on rodents at levels much higher than humans are currently exposed to. But the link between cell phones and cancer in male rats was undeniable.
