It is not OK for chiropractors to claim they can prevent or cure cancer

It looks like something MAY finally get done about regulating the chiropractic profession in Ontario. Complaints are flooding in, not only from critics of the current (extremely lax) regulatory system, but also from chiropractors themselves.
The problem is that there are chiropractors and chiropractors. Most of the complaints are being levelled at the so-called "vitalist" chiropractors, who believe that "subluxations" (impingements of nerves in the spine) can block some putative healing force in the body. Unfortunately, there is no well-founded  scientific evidence that these subluxations actually exist, much less that there is some ill-defined healing force to be blocked by them. Many vitalists also actively advocate against vaccinations. Some vitalists even publicly claim that their treatments can prevent cancer, giving their cause something of a snake oil feel.
An Australian chiropractor who claimed to be able to treat cancer was convicted and fined for false advertising in 2017, and the BC regulatory body for chiropractors recently gave very clear guidelines which say in plain English that there is no acceptable scientific evidence that chiropractic can treat Alzheimer's Disease, cancer, diabetes, infertility, infections, autism, ADHD or Down Sy.drome.
The vitalists, though, are quite an influential group, with four of the nine members of the council of the College of Chiropractors of Ontario (CCO) falling into their camp, and the body has failed to clamp down on such unsubstantiated, even fraudulent, claims. Many chiropractors, as well as other practitioners, are starting to speak out, though, arguing that the body is failing to protect the public, and that it should limit licensed chiropractors to those employing more mainstream evidence-based procedures like the treatment of musculoskeletal problems such as lower back pain. The Ontario Chiropractic Association (OCA) have made specific complaints the CCO, arguing that its continued sanctioning of claims like those about preventing cancer is bringing the practice into disrepute, even though the CCO's own rules say unequovacably that "chiropractors in Ontario cannot make or advertise claims to cure or treat conditions unrelated to the chiropractic scope of practice".
No specific action is being brought against the CCO, and the overseeing government body, the Health Professions Appeal and Review Board, seems loath to get involved, despite the evidence being presented to it. But the outcry is growing, and it seems to be only a matter of time before some long-overdue changes are made.
