Really? No matter how desperately ill you may be, no matter how hopeless your prognosis, you have the right to demand, and the NHS the obligation to provide, every possible treatment for your illness or disease, no matter how cutting-edge and expensive that treatment may be?
If it is available and the treatment is the clinically approved treatment for a certain condition then yes you have the right to demand it and the NHS has an obligation to provide it. Indeed last year there were several court cases that again underlined this essential principle. However like every system in the world resources are finite and sometimes some treatments are just not available - that is a function of living in reality and not a fantasy world.
If you have a disease that can only be treated with a brand-new drug that costs 25,000 pounds a month, NHS will pay for it?
Yes.
If you need a combination heart/lung transplant, NHS will provide it for you, no matter what the cost, even if it means getting a suitable organ donor from Tibet?

No because the time window for organ transportation would not allow it and also UK law does not permit payment for organs. (Although that is a much debated point at the moment.)
