UTMB’s Dr. Eric Walser is among a few doctors pioneering a new prostate cancer treatment that has the potential to draw patients from around the country to the Houston region for care. New technology available in recent years enables physicians to take an image of the prostate, locate the cancer and remove it with a guided laser. Now, with a clear image of where the cancer is, Walser can use an MRI-guided laser to treat precise areas of the organ, all on an outpatient basis.
