Point 1 is only sensationalist if not true. The fact is, there has been little research conducted in the area. This is mostly because, as far as I can tell, there were some supposedly 'definitive' studies in the 1980s which 'proved' there was no effect. Those studies, however, had serious flaws. More research has been conducted recently, some of it very promising, but still mostly of the 'kills cancer cells in a test tube' type rather than the 'large scale double-blind placebo controlled test' type.

Meanwhile, several individual doctors have used the techniques described and report great success.

As for point two, the authors are both retired former academics, not clinicians, and conducting clinical trials is not their area of expertise.
