Study finds thymus gland removal linked to higher cancer risk and mortality

A recent study suggests the thymus gland, often considered 'useless' in adults, may play a crucial role in health. Researchers found that removing the thymus increases the risk of death and cancer later in life. The study analyzed over 7,000 patients who underwent cardiothoracic surgery. Those who had their thymus removed were nearly twice as likely to die within five years and to develop aggressive cancers compared to those who kept the gland. While the thymus is less active in adults, the findings indicate it may still be important for maintaining a healthy immune system. Researchers recommend careful consideration before removing the thymus in surgical procedures.
