Overview

On ultrasound, prostate cancer is characterized by hypoechoic areas.

Ultrasound

• On ultrasound, prostate cancer is characterized by hypoechoic areas

• It seems that size of the area matters

• Small hypoechoic areas (<0.2 cm3) have cancer less than 4% of the time
• One study suggests hypoechoic lesions tend to have a worse outcome; however, this is not supported by an older study
