I think there's an imprecision problem here with the language. What people might mean by "could help" ranges from "A miracle cure overnight" to "3% improvement in perceived severity of one symptom" I hope that people will avoid the former and view the latter in context - i.e. a genuine wish to relieve their suffering for a while, rather than a flat denial of the reality of the disease. I don't think either is especially appropriate, but the latter is misguided rather than malicious.
