More promising techniques

I've been a fan of ablative techniques that don't use radiation since I found out about them late in my treatment plan.  The first I was interested in was Cryoablation, which I was disappointed to find out that I didn't qualify for...part of my frustration with the western medical industry, but that's another story.  I had seen a video about an Israeli researcher who was using ultrasounds to ablate tissues and it seems very promising.  I just recently read a medical publication that identified high-intensity focused ultrasound (HIFU) that had successfully treated a patient in China who had SS.  That is awesome, but...how does a person go about getting treatment in China??? 

That said, why are we dragging our feet so much on an old technology used in a new therapeutic way?  Ultrasound has been used to relieve pain and promote healing in tissues for years.  It is also a primary diagnostic imaging tool.  Taking it a step further and evaluating it as an ablative technique is a sensible and promising method to destroy cancer in a safe non invasive manner.  Hat's off to China for adopting it so readily and treating thousands of patients already!!!
