Nearly one in 10 US adults report having had cancer

The percentage of U.S. adults who report ever being diagnosed with cancer has now reached 9.7% in 2024-2025, a significant increase from the 7.0% Gallup recorded in 2008-2009. The share of adults with a cancer diagnosis in their lifetime registered just over 7% from 2010 to 2015, before starting to climb. It has increased at a greater pace over the past decade.
