Apparently you have never had radiation and chemo treatments or know anyone that has. A person can easily spend $100,000 or more for those treatments and suffer tremendously from the pain associated with those treatments and still not be cured. This is not a cost issue it is the chemo and radiation people doing all they can to stay in business. If DNDN ever becomes successful, the chemo and radiation industry will be destroyed. Ask your male friends if they want to be castrated and wear diapers the rest of their lives. You had better wake up before you have to decided how you want to be treated for Prostate problems.
