Economic impact if cancer was curable

[Del Tachi]

The CDC estimates that only 3.2 years of added life expectancy would be achieved if cancer was totally eradicated.  That's because, as pointed out above, most cancer deaths are elderly so its eradication would still leave a host of other age-degenerative diseases, like Alzheimer's, to kill those who would have otherwise died of cancer.  The most promising prospect for life-extending medicine lies in treatments that slow the age-degenerating process itself, like Metformin.
