A new study suggests that accelerated biological aging may help explain the increasing rates of cancer in adults under 50. Researchers found that younger generations showed a greater gap between their biological and chronological ages compared to older generations. People with the highest biological age scores had about a 15% greater risk of developing early-onset solid cancers, particularly lung, gastrointestinal, and uterine cancers. While the findings do not prove that faster aging causes cancer, they offer important clues about why cancer diagnoses are rising in younger adults. Scientists stress that larger studies are needed to confirm these results and better understand the underlying mechanisms.
