I wrote a piece for Boing Boing about tonsillectomies that has just been posted. It stemmed from a comment on this blog by a woman named Rachael. A doctor said her son should have a tonsillectomy. When Rachael did her own research, however, it seemed to her that the risks outweighed the benefits. I looked further into tonsillectomies and found that the risks were routinely greatly understated, even by advocates of evidence-based medicine.
