The Prostate Cancer Research Institute (PCRI) has produced several short videos covering many aspects of the disease including, imunotherapy, brachytherapy, intensity-modulated radiation therapy (IMRT), sexual disfunction, testosterone levels, and more. The speakers include Dr. Mark Moyad, Dr. Eugene Kwon from the Mayo Clinic and others. It is my understanding that such videos will become available on an on-going basis. One can obtain these videos by subscribing to Google below.
