Thymus removal tied to increased mortality and cancer, surgeons urged
Technology
A recent study says that adults who have their thymus gland removed are almost twice as likely to die within 5 years and twice as likely to develop cancer within 5 years compared to those who keep it.
This challenges the old idea that the thymus doesn't matter after childhood.
Harvard's Dr. David Scadden points out that the gland still helps make important immune cells, so surgeons should try to leave it in when possible.
Yale study finds no extra risk
On the flip side, a 2025 Yale study found no extra risk after thymus removal for adults with certain conditions.
Both research teams agree: we need more answers about how losing your thymus affects long-term health and immunity.
