FYI: I sent an e-mail to BDG regarding this, but others might want to know about a dedicated mammography machine that saw demonstrated in Castro Valley California about 5 years ago that allowed the patient to control the movement and pressure of the paddle. Using a button she held in her hand, she could "push the limit" of the pressure, knowing that she had full control of when it stopped coming down. The results have been that the average mammogram has been better, due to the fact that the women were compressing more than the technicians do. I have not heard about a non-compressing mammography device.
