High-intensity focused ultrasound (HIFU) can control prostate cancer with fewer side effects

In recent years, a new treatment strategy known as focal therapy (partial gland ablation) has emerged for prostate cancer considered to be "intermediate risk"—mostly, small tumors confined to one area of the prostate. At Memorial Sloan Kettering Cancer Center (MSK), researchers have been working closely with an advanced focal therapy approach known as high-intensity focused ultrasound (HIFU), guided by magnetic resonance imaging (MRI).
