Are cancer rates really on the rise?

One side of this issue says cancer rates are not rising but because of advanced techniques for detecting it and people living longer it just seems this way. On the other hand there are those who think cancer rates really are on the rise overall, that more younger people are getting cancer than ever before and these rates will continue to rise in the future. They can’t both be right so which one is it? Is cancer really on the rise and will it continue to get worse or vice versa? Just peoples’ opinions or facts here.
