Mayo Clinic expert calls for public health measures to improve diet, reduce cancer risk

A review article by Mayo Clinic researchers emphasizes that early onset colorectal cancer, defined as being diagnosed when younger than 50, continues to steadily increase in the U.S. and other higher income countries. This increase, along with a decline in later-onset cases due primarily to screening have shifted the median age at diagnosis from 72 years in the early 2000s to 66 years now.
