[Early diagnosis of breast tumors:/is echography conclusive?].

The use of ultrasonic scanning in examination of the breast is discussed. It is felt that this method is the best that science can offer at present for this purpose, its superiority lying in its diagnostic dependability (90-95% exact diagnoses), low detectability limits (lesions of 5 mm can be diagnosed), suitability for the examination of breast of every age and size, complete freedom from risk, and systematic repeatibility.
