The problem is not that Halassy used self-experimentation as such, but that publishing her results could encourage others to reject conventional treatment and try something similar, says Sherkow. People with cancer can be particularly susceptible to trying unproven treatments.
I think they're going to try unproven treatments regardless, especially if there's a high barrier towards conventional treatment. The difference is whether they'll be swindled by quack cures or use something with demonstrable effects.
And the "proven" (chemo) treatments make your life hell. The balding, nausea and weakness that cancer patients experience is mostly from the treatment itself.
My uncle has had cancer a few times and i cannot describe the hellish side effects. Im glad he is still around, dont forget to spend time with people you love, its worth it!
