The subjects involved in the present study were 136 patients with breast cancers who had undergone ultrasonographic examination in our hospital during the past two and a half years. All cases have been diagnosed for breast cancer histologically. The authors conducted study which compared palpation and ultrasonography to macroscopy on cleavage planes as methods to accurately determine the diameters of tumors (referred to a CS, SS and MS respectively) located at varying depths (D). The diameter of each tumor was evaluated by each of the three methods and the results were grouped according to depth of the tumors for compression.
The results were: for group A (D>20 mm, 104 patients), CS=27.8±10.9 mm, SS=20.5±8.3 mm, MS=21.5±8.8 mm (Mean±S. D. in each case) and the correlation coefficient (r) between CS and MS was 0.73 (p=0.01), and r between SS and MS=0.91 (p
