In a small study of 80 women, doctors used the technique called ‘elastography’ to distinguish harmless lumps from malignment ones with almost 100 percent accuracy. When checked against biopsies of women’s breast tissue, the ultrasound technique correctly identified 17 out of 17 cancerous tumors, and 105 out of 106 harmless lesions. The technique was first used in the 1990’s at the University of Texas Medical School of Houston by Jonathan Ophir. Ophir says elastography is a way to measure and picture the elasticity of body tissue. The findings were reported at a national radiology meeting in Chicago this week.
