The use of ultrasonography is controversial. High-frequency (20 MHz) and ultra-high-frequency (40-100 MHz) ultrasound systems have been used; their accuracy in delineating malignant lesions from benign lesions remains inadequate, however, with a success rate of approximately 20%. Furthermore, the claims of reliable tumor sizing and depth of invasion are promising but still passionately debated.
