Pope Leo Undergoes Surgery: Doctors Confirm Cancer Diagnosis

Pope Leo XIV, 71, was admitted to Rome’s Agostino Gemelli University Hospital on October 13, 2026, for surgery to remove a lung nodule.

The Vatican canceled his public audiences through October 20 and modified several religious engagements as doctors prepared for the procedure, which is expected to require approximately one week of hospitalization.

The Holy See Press Office confirmed that doctors had discovered a «small, localized nodule» in the pontiff’s lung during routine medical examinations. Vatican spokesperson Matteo Bruni said the medical finding prompted doctors to recommend surgery.

Officials have not announced a cancer diagnosis, and the precise nature of the abnormality has not been publicly established.

The Vatican confirmed that Pope Leo XIV successfully underwent surgery to remove a lung nodule on October 13, 2026, at Rome’s Gemelli Hospital.

The procedure was performed by a specialized thoracic surgical team under Professor Stefano Margaritora. Following the successful operation, the pontiff returned to his hospital room to begin an expected weeklong recovery.

The Vatican confirmed that the operation would be performed by Gemelli Hospital’s thoracic surgery team under Professor Stefano Margaritora. The procedure was scheduled for Tuesday afternoon following the Pope’s admission.

Doctors are expected to remove the nodule for further examination, while Vatican officials said additional medical information would be provided after the operation.

The Prefecture of the Papal Household announced that the Pope’s official audiences would remain suspended through October 20. Leo XIV had maintained his scheduled meetings on Monday, October 12, just one day before hospitalization.

His absence requires adjustments to several Vatican gatherings, including religious celebrations and meetings involving senior Church officials.

Among the affected events is the October 14 Mass commemorating the tenth anniversary of Amoris laetitia, Pope Francis’ apostolic exhortation addressing marriage and family life.

Cardinal Luis Antonio Tagle was assigned to preside over the ceremony instead of Leo XIV, while organizers also adjusted the accompanying conference and postponed its concluding report.

Jesuit Father Giacomo Costa, involved in organizing the Amoris laetitia anniversary gathering, addressed the changes and emphasized support for the pontiff.

«During the Mass, we will pray especially for the Holy Father’s health, as well as for families,» he said. The celebration will proceed despite Leo XIV’s absence from the scheduled religious events.

The hospitalization represents the first significant medical issue publicly announced since Leo XIV became Pope in May 2025. Born Robert Francis Prevost, he became the first American-born pontiff following the death of Pope Francis. His disclosure of the medical abnormality offered Catholics an unusually direct explanation of the circumstances leading to his surgery.

Rome’s Gemelli Hospital has previously treated several Catholic leaders, including John Paul II and Francis. The institution became internationally recognized for its role in managing serious papal health conditions. Leo XIV’s admission has renewed attention to the Vatican’s medical communication practices and arrangements for maintaining Church administration during a pontiff’s hospitalization.

Messages of solidarity have arrived from Catholic communities and political leaders worldwide. In Rome, Cardinal Baldassare Reina arranged prayers at Gemelli Hospital, while parishes and religious communities were encouraged to participate. Cardinal Pietro Parolin, the Vatican’s secretary of state, also expressed confidence in the Pope’s medical care and his preparation for the procedure.

The Pope’s planned November 6–17 journey to Uruguay, Argentina and Peru remains on the Vatican’s calendar despite his hospitalization.
