Wow! Thank you so much for sharing that link. So incredibly sad and tragic. I for one feel people should be aware of all the "what ifs". Doctors are human beings and unfortunately this was a tragic, tragic accident. Hopefully bringing this out in the open will make people ask the "important" questions. I know we certainly grilled everyone involved with John's radiation treatments BEFORE he started treatments inquiring as to how the equipment works, how they know where to direct the beams etc.
