X-ray tech here, but I’m not a mammographer. For some silly reason, women don’t seem to want guys to do mammograms. 
Anyway…regarding the pressure…
The harder the squeeze, the better the image. I believe that most places average about 20 pounds of pressure (I haven’t checked lately). Uncomfortable, no doubt. But just remember, the machines can go up to over 40 pounds of pressure. :eek:
They get great images at 40 pounds, but oddly enough, they don’t get as much return business.
The images they’re trying to resolve are tiny–sometimes less than 1/50th of an inch. That’s the reason for the squeezin’–to be able to view the image as distinctly as possible.
Heh. When I was in rad tech school, and they mentioned the amount of pressure applied, one of my classmates said, “That’d be like Devon standing on 'em!” Devon was her little boy. Kind of put it into perspective for me.
Bless ya, ladies. I hope they come out with something better soon.
cervaise asked about IBTCers. The machine pinches all the way back to the muscle. In fact,at least a “fine edge” of muscle must be seen on the edge of the film, or else that means the exam is incomplete and must be repeated. So, small breast size isn’t a problem.
Cowgirl Jules mentioned an MRI. I just want to pass on that, if it’s done like I’ve seen before, it’s another one of those “check your modesty at the door” things. First, you lie on your back for the first series of images. Then you roll over and place your chestal appendages dangling through a couple of round holes (breast coils). (You’re generally wearing a paper gown and reverse it after the first series of images.)
I think this process was devised by Dr. Aaron M. Out.
