Cancer is rising in younger adults. Faster biological aging may help explain why

What the research found
Study (observational). WashU Medicine’s Yin Cao, Ruiyi Tian and colleagues report in Nature Medicine that among more than 154,000 UK Biobank young adults and more than 10,000 U.S. All of Us participants, more recent birth cohorts looked biologically older at the same chronological age. U.S. adults born 1990–1999 had systemic aging 92% of one SD higher than those born 1965–1969; UK 1965–1974 vs 1950–1954 was 23% of one SD. Greater systemic aging tracked an 8% higher risk of early-onset solid cancers (diagnosed at 55 or younger); the top tertile had 15% higher risk after genetic adjustment. Organ-specific clocks linked immune aging to lung cancer and adipose aging to colorectal cancer. Association is not a screening protocol. Educational aging notes, not a diagnosis.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
