My Fathers PSA level was about between 5 - 10 but now it is 46

My Father has PC and he has been using Cazodex injections from his doctor (inserted in the stomach region) along with Cazodex tablets (Bitatotamine). He was able to contain the PSA under 10 for about 4 yrs but during 2011 until now it has risen to about 46. He lives in the Seychelles Islands and doesn't have access to specialists, medication, alternatives, medical treatments for PC and he doesn't know how to use a computer. I live in Brisbane Australia and I have been trying to do all the research for him to find something that will help. I am gettig frustrated and confused because everthing I reseach has conflicting stories and evidence about the product. He heard about 714x from Canada and he is tryingh to get me to buy it for him, I researched it and it sounds like a fraud.....i am running out of options so can someone please give me some facts or ideas about treatment to reduce his PSA and keep it at bay for at least another 10 - 15 yrs as he is a very fit healthy 60 yr old man.
