Doctors have come up with a revolutionary new mammogram that is radiation and pain free! They are using ultrasound technology to detect tumors in the breast. Radiologists from the Karmanos Cancer Institute in Detroit, USA, suspend a woman’s breasts in water and fire ultrasound rays through them to generate images of the breast tissue. Not only is the new method pain free, it is said to be more accurate at picking up cancer than a traditional mammogram and uses no radiation so it’s safer for the patient.
