All else equal, LL price should be going down in the long-run.
The reason you may see LL price going up is because some new CLL doctor low-ball in the beginning to attract patients and once they have a successful track records and people start coming to them, they raise their price. This happens to, perhaps, China (24k before but over 33k now), South Africa and some indian doctors. Adjusting for inflation, the price of some of the mainstream doctors have either stayed the same or decrease a little.
But I agree with Blackhawk and TomD
Everything else being equal LL price should decrease over the long-term. Here is why.
CLL is relatively new. The number of doctors with successful track record are few. The procedure is also dangerous so people is willing to pay a higher premium for higher level of safety, making the price inelastic. For, example, a CLL doctor can perform on only 3 patients per week. But 10 people come to him for CLL and they all varies in income range. The doctor would set his price point so that only 3 rich patient can afford this surgery and the rest can't. This is the natural law of supply and demand at work.
But over the long-run, as more doctors realize the economic benefit of performing this surgery and enter the industry, supply meets demand, the price should decrease. You can learn this in any economic class.
One dude who wants you to think that LL will rise in price and that you should do is now is Sysop/Apoth/sysop... so he can earn his commission now.
I imagine a day in the distance future when a broker you meet on the street can do LL for you on a loan... like the movie below.
