Its amazing how many people think cancer is curable, you simply go into remission and hope to god the treatment and your body keep it that way, but ultimately something will get you eventually, we are not designed to live forever, we are actually quite a fragile race, with people like TB showing how far we can be pushed, with help.
Although it does amaze me how in the future cancer will be looked at like the common cold is, and likely curable with one pill, but we are a ways off yet.
