Ever since the first tort suit that claimed a link between phone radiation and brain was filed in 1993, research into the subject has fallen on all ends of the spectrum. The latest is a study that found we absorb more radiation from cell phones than previously estimated, according to research published in the journal Electromagnetic Biology and Medicine. A look at just some of the studies from the last five years show just how muddled all the research has gotten.

2007

Cell phone use is okay for brains ... in the short term.

Then again, long term use might increase risk of brain tumors.

2008

Wait, actually phones present a greater risk than smoking.

Whatever the findings, scientists urge Congress that the link might exist, pointing to several studies.

2009

Oh phew, new evidence shows that there's no connection between talk time and tumor development.

Nevermind: The World Health Organization announces cell phones are not as safe as we thought.

2010

"An increased risk of brain cancer is not established from the data" finds a study.

"10% of people who used their phones most often and for the longest period of time ... had a substantially higher risk of developing some form of brain cancer than those who didn't use a mobile phone at all", finds the same study. 

2011

Cell phones change brain activity, uh oh.

Talking on a mobile phone "possibly" causes cancer, found the World Health Organization.

And now, today's finding: Cell phones make us absorb a lot of harmful radiation.

All the studies add up to no concrete answer. But would you hold a maybe cancer machine up to your head?
