Younger Cohorts Age Faster, Boost Early Cancer Risk 15%

6/26/2026

Summary

Story summary

Washington University researchers published a June 22, 2026 Nature Medicine study showing younger generations age faster, with UK 1965-1974 cohort 0.23 SD higher than 1950-1954 peers and U.S. 1990-1999 cohort 0.92 SD higher than 1965-1969 peers.
Greatest systemic aging raised early-onset solid-cancer risk 15% and each SD increase added 8% risk for lung, gastrointestinal and uterine cancers.
Immune-system aging linked to lung cancer, while fat-tissue aging linked to colorectal cancer.
