This ScienCentral article and video is a great example of the way in which cancer research is driving our understanding of human biochemistry. What we call cancer is, in essence, a laundry list of runaway failure modes in the very complex biochemical machinery within our cells. If you want to prevent a machine from breaking down, or repair a failure in process, it helps to have the relevant blueprints to hand. By the time cancer is reduced to the status of costly but non-fatal chronic condition - perhaps as soon as 2015, at least for the most common classes of cancer - if seem likely that our understanding of cellular biochemistry will be nearly complete. If cancer research produces blueprints for human biochemistry, scientific anti-aging research - and every other field of modern medicine - will certainly run with them.
