“The question is if then, is it worthwhile to take on any risk?”
The question is if it helps.
For patients that are already very sick, that we know it does not help, for the patients that are still at the early stages of the disease some are arguing that it does help.
As of yet, there is no conclusive evidence to this, some argue that desperate times call for desperate measures. Usually, we like to have clear evidence before a treatment protocol is widely accepted.
If this treatment turns out to actually be effective, the potential risk for most patients is minimal.
