Thymus health linked to longer life, new AI study finds

AI analysis of CT scans shows adults with healthier thymus tissue have around 50% lower risk of death, 63% lower risk of heart disease, and 36% lower risk of lung cancer, challenging the idea that the thymus shrinks and becomes irrelevant after puberty; a second study also linked thymic health to better responses to cancer immunotherapy, suggesting thymus health could help gauge aging risk and guide treatment.
