That they are but one is nowhere near as dangerous to the herd as the other. I don't see a need to lump these camps together.

The infectious ignorance can kill those who get treatable cancer. Watching someone die from cancer hurts those around them, leaving scars.

It’s not that different.

One is to prevent the whole herd from being infected(eradicated possibly), the other is a sick member to choose their way to treat themselves. Grievance is a part of life, it is sad to see members go, but I can't compare between that and the herd disappearing completely(no one left to grief).

EDIT: also I can't help but feel that this claim puts Chemotherapy on the same level of effectiveness as Vaccines. I think all options should be exhausted before we start claiming chemo to be as miraculous as vaccines are.
