- In recent decades, cancer rates have been climbing among people under 50, the typical cutoff for when cancer is considered “early-onset.”
- In the U.S., the rate of early-onset cases rose by almost 18% between 2000-2019, even as cancer declined slightly in older adults.
- Among Americans between 15-39 years old, an age group cancer researchers refer to as adolescents and young adults (AYAs), the surge was more pronounced still, topping 20%.
