Urine Therapy for Follicular Lymphoma?

And I thought I'd heard (almost) everything. John Bettens says that he has kept his follicular lymphoma at bay for going on three years now, by drinking one cup of his own urine every day. Maybe. I honestly do hope that Bettens's tumours continue to shrink, and disappear, and stay that way. But I also have to say that I genuinely can't see how that would be related to urine.

The statistical record shows that around one in four or five lymphoma patients experiences meaningful regression (shrinking) of tumours, and most of the rest of follicular lymphoma patients still have a very slow disease course. This makes it a very ripe field for misleading anecdotal evidence.
