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

Accelerated biological aging in more recent birth cohorts is associated with a higher risk of early-onset cancers in adults under 55. Researchers found that younger generations tend to exhibit greater biological age acceleration compared to earlier generations at the same chronological age. The link was particularly pronounced for lung, gastrointestinal, uterine and colorectal cancers. The findings offer a mechanistic clue to the well-documented global rise in cancer incidence among younger adults.
