Pope Leo XIV Diagnosed With Lung Cancer, Undergoes 90-Minute Surgery
Pope Leo XIV has been diagnosed with lung adenocarcinoma and undergone 90-minute surgery to remove a lung nodule. The Vatican says the operation was completed without complications as his public engagements through October 20 are cancelled.
According to reports, the 71-year-old Pope Leo XIV was diagnosed with lung adenocarcinoma, a type of lung cancer. The development marks the first major health problem to emerge during his 17-month tenure. On Sunday, during a prayer service, the Pope disclosed that doctors had detected a nodule in his lung and said he would have it removed.
Two people familiar with the developments, speaking on condition of anonymity, said the operation began on Tuesday evening. The surgery was completed without complications and took around 90 minutes. The Vatican said Pope Leo regained consciousness normally after the procedure and was resting in his hospital room. Medical experts reportedly believe his chances of recovery are very good because the nodule was removed at an early stage.
Pope Leo is expected to remain in hospital for approximately one week following the surgery. In view of his recovery, all his public and official engagements scheduled through October 20 have been cancelled.
Looking ahead, Pope Leo is scheduled to undertake an 11-day tour of Uruguay, Argentina and Peru from November 6 to 17. His recovery and the cancellation of his immediate engagements come as the Vatican manages the implications of the health condition affecting the head of the Catholic Church.
The Pope occupies the highest religious office in the Catholic Church, which has approximately 1.4 billion followers worldwide. There is no official position designated to take over the Pope's responsibilities when he falls ill. However, the Vatican's administrative operations continue during such periods.
Pope Leo, whose birth name is Robert Prevost, was elected by cardinals from around the world in May 2025. Born in Chicago in 1955, he spent several years serving as a missionary and bishop in Peru before becoming head of the Catholic Church. His predecessor, Pope Francis, died in April 2025 at the age of 88.
The diagnosis, surgery and temporary suspension of official engagements have placed Pope Leo's recovery at the centre of attention as the Vatican continues its administrative work and prepares for his scheduled international tour in November.
