>>That is a good question. My first reaction is to say yes, why not? Seems like if there was an opportunity to save someone from getting cancer it shouldn't be hindered by someones religions point of view.
What about cigarettes in that case. Making them illegal would avoid lots of cancers and respiratory and cardiovascular disease. I don't think there would be religious objections to that and removing access to poisons is far less invasive than forcing injections on somebody against their will.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
