Your upper chest could be the key to your longterm helath. A new study found a correlation between the health of a human’s thymus and the likelihood of cardiovascular disease or cancer. 

Published on Wednesday in the science journal Nature, researchers detailed how the thymus is “crucial” for long-term health and lifespan, reshaping prior assumptions about the organ. 

“These findings reposition the thymus as a central regulator of immune‑mediated ageing and disease susceptibility in adulthood,” the report reads. 

Thymus Health a Key Indicator

Using AI tools, scientists analyzed more than 27,000 patient scans and medical records to evaluate thymus health. According to the journal, people with high thymic health had a mortality rate of 13.4%, compared with 25.5% among those with low thymic health.

The thymus, a two-lobed gland sitting in the upper chest between the lungs, is responsible for T-lymphocytes, white blood cells that protect the body against pathogens and diseases.  

Throughout the years, the thymus “decays with age” turning a once enlarged organ for health, into fatty tissue replacement as it shrinks. 

The report added that 5.3% of people with low thymic health developed lung cancer, and that 16.7% of people with low thymic health developed cardiovascular disease.
