Scientists Say This Overlooked Organ Could Hold the Key to Longer Life

Researchers at Mass General Brigham used AI analysis of CT scans to show that healthier thymus tissue in adults is linked to lower mortality and reduced risk of cardiovascular disease and lung cancer.

The findings challenge the long-held view that the thymus matters only in childhood and suggest it may be an important marker of aging and overall adult health.

A healthier thymus was also associated with better immune function, including greater T cell diversity and stronger responses to cancer immunotherapy.

Based on data from the Framingham Heart Study and a lung cancer screening program, the research points to new opportunities for disease prevention and personalized cancer treatment.
