unless you keep your cell phone a few cm away from your body physically you are generally exposed to above thermal limits (assuming you have airplane mode off and data or wifi enabled). Even the periodic tower pings may be above thermal limits, though typically they are short burts over very high intensity.

And then there's this risk (below) which should make you think twice about putting your telephone in your pant or jacket pockets.

And now back to the thermal limits. If you are exposed above thermal limits you are raising your cancer risks. This was known since the 40s (eg ww 2 radar operators) and is well established. In the past few decades the only debate was whether sub thermal limits of microwave and UHF and higher frequency RF raises cancer risks; the evidence is slowly piling up, and it seems those urging caution are being proven correct.
