Colon cancer deaths rise among Americans under 50, now leading cause of cancer death in that group.

The articles center on colon cancer in Americans under 50. One report notes a rise in deaths from colon cancer within this age group, reporting that the disease has become the leading cause of cancer death among Americans under 50.

A separate study cited in the collection suggests that under-50 Americans who don’t smoke and have better-than-average diets may be more at risk of developing colon cancer.

Together, the reports present a concerning portrait of colon cancer in younger adults, combining a rising mortality trend in a defined demographic with an apparently counterintuitive risk profile based on smoking status and diet.
