As noted, you'd be surprised that many chemo regimens these days are almost side-effect free (especially after the anti-side effect stuff is given, like anti-nausea and anti-diarrhea agents). They are NOT "literal torture."You speak in absolutes, which is not conducive to civil discourse... but AFAIK, there is some truth in your comments. I think we all agree that chemotherapy is basically semi-targeted poisoning of a human body. I think we can all agree on THAT, at least.
People should be empowered to educate themselves and make their own decisions. Personally, if I had terminal cancer, or even just really advanced cancer... I'd rather get into Pain Management and Salvage The Time I Have Left, than subject myself to literal poison-based torture.
Some of them still are very unpleasant. But this very much depends on the disease and the drugs and doses to be used. No generalization is possible.
