A search for "cell phone" in Google news this morning pulled up two articles related to the now decades-old debate of whether or not cell phones really do cause brain cancer, one for each side. On one side, we've got Dr. Oz, who went on Oprah two days ago to say that cell phones still might cause problems and that he doesn't think studies have been in-depth enough to cover the full extent of phone usage. On the other side, we have a report of a Danish study covering people who had used cell phones for up to 21 years and found cancer rates no higher than the national average. I've got no medical training that would tell me one way or another who to believe, but it's interesting to see that there still seems to be no definitive answer to this debate.
