Germs vs. Cancer

This article is about an interesting theory in cancer research. The idea is that infections force the body into combat-mode, thus making the immune system much more capable at destroying cancer cells. One example they site is that people who have had severe acne, caused by bacteria in the skin, are less likely to get skin cancer and lymphoma (I guess I should have wished for more pimples in my teenage years).
Anyway, for obvious reasons I am starting to find cancer research interesting. What fascinates me the most is that they haven't figured cancer out yet. It amazes me to think about all that we know, and all we can do, and then to think about all that we still do NOT know and can NOT do. 
I'm realizing we aren't as clever as I thought we were. But we'll get there in a not too distant future - unless of course the current trend towards anti-intellectualism (I miss Ze Frank) gets in the way mucks eveything up.
