Electrical Breast Cancer Detector Under Study

A painless, portable device that uses electrical current rather than X-ray to examine breasts for cancer is under study at the Medical College of Georgia (MCG). MCG is one of some 20 centers across the world studying impedance scanning, a technique based on evidence that electrical current passes through cancerous tissue more easily than normal tissue. Preliminary studies have shown the technique, which takes about 10 minutes and doesn't require often-uncomfortable breast compression, can pick up very small tumors, according to its developers, Z-Tech, which has offices in South Carolina and Ontario, Canada.
