Zytiga Available on Greek NHS

My father has been suffering from prostate cancer for 20 and a half years. Over the years his body responded well to a variety of drugs and thanks to research he has been able to fiight his desease. He is currently 85 and taking Zytiga (Arbiraterone Acetate) in Greece through the Greek NHS system. It has cut his PSA count by half in 6 weeks! It has given him new hope and is able to enjoy life. He is currently not counting months.
I am surprised that in a country like the UK the NHS cannot find the money to help people when millions are squandered elsewhere.
