You make a very good point.
We'd all die from cancer if we lived long enough. It sounds a bit warped, but if you live long enough to get cancer, it usually shows you've done something right--e.g., you didn't do something young and dumb like drugs or drinking and driving.
I'd rather be an average American with a lifespan of 75 and a much higher risk of cancer than an average Indian with a lifespan of less than 60 with a lower risk of cancer.
