Instead of using harmful radiation or painful procedures, the Z-Tech Breast Cancer Scanner simply measures changes in electrical resistance in the breast in order to detect tumours. If one breast is more resistant than the other, it indicates the potential for cancer. This works best on dense breast tissue, which is also hardest to scan with current methods. A twelve-part electrode attachment, resembling a plastic flower, is attached to the breast, in order to scan it from all directions. "Our device is really a screening device," says developer Nakashige. "It's more of a yes-no answer that you get. You just want to determine whether someone should go on for diagnostic [mammography, ultrasound, or MRI] testing or go home." [GT]
