If you don't die of something else first, cancer is what will get you. Increased cancer rates are merely a side effect of improvements in other aspects of health and longevity.
That's part of it, but there legitimately has been a significant increase in cancer rates among younger people. There's something going on but we don't know whether it's radiation or food or something else.
Cancer rates continue to rise, and will be well over 50% of all people in my lifetime.
There is no doubt our current world is making us very sick.
