> Millennials born in 1990—at the peak of the generation—are twice as likely to develop colon cancer as Baby Boomers born in 1950.

I understand this is not necessarily the point of the article, but how is this not considered a massive crisis? I have heard this stat mentioned before but never with much urgency or impetus to determine the cause of what appears to be a massive health crisis introduced in fairly young generation.

Is it our diet? It's hard to imagine that millennial diets are that much different than what was/is eaten by older generations. Certainly older generations also had their own major carcinogenic lifestyle factors to contend with in terms of smoking and chemical exposure.
