I just wanted to put in a nice word for Penny Brohn. They very careful position themselves as complementary, not alternative, to conventional cancer treatment.

There was some work that looked at the outcomes of the Bristol Cancer Help Centre that showed poor outcomes, but that research didn't correct for the illness of the patients. Lots of people using the service were on palliative care pathways and were expected to die. They were using the service to get the death they wanted.
