"You wouldn't download a new lung, would you?" (RIAA ad in 2033). I lived in a tent 200m downwind of a 24x7 burning trash dump on a former Iraqi and then USAF military base, for some time, so I think I've got particulate risk checked already.
I think I actually hope my odds of eventually getting cancer are ~100% over my lifespan, because it seems to be a natural consequence of living long enough. I also hope that by the time I have cancer of any size, it is something you can treat fairly successfully.
As long as they treat cancer as a profit center, a cure will never surface in the US of A. "Treament" is a multi billion (trillion?) business, a cure would reduce that to dust.
Also, you should look up the agony, people would rather shoot themselves than take the "treatment"
I don't think the situation was that bad. The one really unforgivable thing was shoddy electrical work in shower trailers (I think ~10 contractors and soldiers were fatally electrocuted while showering while in Iraq! I certainly got 230v a couple times and went through the reporting process, and actually got MPs and a friend from Contracting to turn it into a bigger issue.)
