I am sure a breathalyzer test would be much less expensive than a mammogram (no leaded walls required, no certification of technician, inspection by the radiologic safey people, takes less time (thus more patients per hour), no malpractice coverage required as no radiologist required to read it, also no "professional service" fee for the reading...

There is a lot of competition from firms tryiing to develop machines to look for small quantities of organic materials ( goded on by the hope of large
profits in the Home land security field)--my neighbor has one such company, trying to decide how to market his machine.

The only losers would be the radiologists and makers of mammogram machines and they are already moving into more lucrative alternatives --"interventional radiology" and cyberknife.

But why not use dogs in those places which can't afford a machine and save a poor stray from the usual fate of euthanasia?

I wonder what the dog would charge you--a pet on the snod or a dog treat?
