The 14 breast cancer, with have been confirmed by pathology, have been studied with the criteria described above on the diagnostic accuracy. The diagnostic accuracy with echography has been 78.6% in this series.
As the results, with the high resolution echography by 7.5 MHz polymer transducer, the diagnostic accuracy of the breast cancer in less than 2 cm in diameter has been found still unsatisfactory.
