Notice that the legacy health website is the website of a facility that uses the Novalis machine. For several reasons, some honorable and some not-so, they are not going to say that the Novalis is second-best. Some of Mark's quotes come from websites dedicated to promoting the cyberknife, and they likewise won't say the the cyberknife is second-best. The brochure that my hospital gave me for their Linac Scalpal made it sound as if I'd be an idiot to choose another machine.
Mark has been giving out good information on this board for a long time. What he says is backed by studies that he has read and, in many cases, graciously posted. He really is a blessing, and you'd do well to pay attention to his comments. However, even with medical testing, there is a need to exercise care. For example, there is a wretched excuse for a "study" out there that determined that there is no difference in control rates between radiosurgery and no treatment at all. It's BS of course, but unless you read the study carefully it might sound plausible. Personally, I would like to see more long-term studies with larger numbers of patients before conclusions are drawn, but that's just me.
If you're confident in the Novalis, that's great. I'm sure your doctors, and the machine, will do a super job. However, I feel that you'd be selling yourself short if you base your decision solely upon the statements of Novalis-promoting websites and Novalis-operating doctors.
We all wish you the best!
