It's naive to believe that everybody is in it for the right reasons.
I work in healthcare and am a cancer survivor myself, so I kind of look at this stuff from two points of view. I wholeheartedly agree and believe that there are brilliant, good people working on this type of stuff all the time. Just like I know the team of experts I worked w/ were looking out for me. I just also know "big" corporate type interests can play in to this type stuff. The pharmaceutical industry or "big pharma" is about money, and there is a lot more money in treatments than there is in cures.
I'm not saying it's a "conspiracy", or doubting the intentions of any individual scientist/researcher/doc, I just take into account how much money and the current system play in here. The other thing, is the "cure" for cancer will never exist. There is to much variance in the types, causes etc. In my opinion the real "cures" will come from prevention, not treatment. Again, not saying we shouldn't work on both.
Anyway, just my opinion. Fuck cancer, I hope we all live in a world w/out it (or at least A LOT less) at some point, no matter how that happens.
