|Detecting breast cancer in young women|
A new test that uses electrical impedance scanning (EIS) is proving to be a promising tool for detecting breast cancer in women younger than age 45. Researchers grouped more than 1,100 women according to their breast cancer risk based on clinical and biopsy findings and had them undergo EIS, which measures electrical signals as they flow through the breast. The scans were often positive for the women with the greatest cancer risk but rarely positive for those with the lowest risk. The U.S. Food and Drug Administration has approved EIS for use in diagnosing tumors detected by mammography, but approval for use in breast cancer screening awaits further clinical testing.
