The ability of RF to penetrate the body also goes down with increasing
frequency. Also at incresing frequency the ability to focus RF power
becomes easier and the antennas more compact adding to the
the risk.

All RF should be considered with care. IT's energy radiated and if
you are in a concentrated field (IE: in front of a dish antenna) then
the risks go up as compared to a diffuse field.
