DEAR DR. ROACH: I have prostate cancer. My PSA levels were as high as 48, and I’m taking medication to lower the numbers to 40. My urologist has recommended a high-intensity focused ultrasound after reviewing my MRI and biopsy results. Apparently, the cancer has not spread beyond the prostate. I was told that this procedure is much better for recovery purposes, as well as for quality of life afterward. The procedure is done via sound waves to focus on the area without having to damage anything around it. When the doctor explained to me that I would not have any of the side effects from the standard surgery, I was on board. Have you heard of HIFU, and if so, what do you think about it? -- J.W.
