The only officially recognized effect of microwave exposure is heating. That is written into US (and probably other countries') regulations in black and white.
In actual fact, at low radiation levels, modulation is critically important. With judicious modulation, you can easily disrupt critical biological processes involved in growth and healing, at about any wavelength with very low power level.
But it is fairly unlikely that on a Starlink plate searching desperately for a satellite you would get modulation of a character to induce such effects.
Likewise your typical 5G phone or tower. But nobody knows, because literally nobody has checked. Actually checking would be extremely hazardous for anybody with any sort of stake in 5G or Starlink, opening them to various sorts of liability lawsuit for failing to disclose harm found, or failing to discover whatever harm is later found. Not checking at all, though, is A-OK!
So the experiment is being run on the general public, instead. Again. Happened with 4G, 3G, 2G, analog cell, each with its own modulation scheme and mix of wavelengths.
Cancer mortality rates go up, down, sideways, and nobody generally knows why.
