Pope Leo Recovers After Lung Cancer Surgery
The 71-year-old pontiff returned to public duties after removal of part of his right lung, with doctors saying no further cancer therapy is needed.
Updated on Nov. 3, 2026 in Cancer
Pope Leo underwent surgery on October 13, 2026, to remove the lower lobe of his right lung after being diagnosed with lung adenocarcinoma. Pathology findings indicated the cancer remained localized and had not spread, and he has since been discharged and returned to St Peter's Square for his weekly audience.
Why it matters
The surgery and clean pathology results address a high-profile health question for the head of the Catholic Church, who was generally considered to be in good health before the diagnosis. The case offers a concrete example of localized lung cancer treated with surgery alone.
Pathology analysis of the removed tissue confirmed lung adenocarcinoma that remained localized without spread to other tissues. The pontiff is 71 years old, and whether he will undertake his planned November 6-17 South America trip has not been determined.
The players
Pope Leo
The head of the Catholic Church and sovereign of Vatican City, whose health and travel plans are the focus of this story.

Vladimir Putin
The President of Russia, with whom Pope Leo held a telephone conversation during his hospital stay.
The details
Lead surgeon Stefano Margaritora removed the lower lobe of Pope Leo's right lung, and lung cancer was confirmed through histological examinations and molecular biology analyses of the removed tissue. Vatican officials said the pontiff will gradually resume his activities and may need to adjust his schedule pace during recovery.
Timeline

Historical Context
Pope Leo's return to public duties after lung cancer surgery follows the precedent set by Pope John Paul II, who resumed his schedule after his 1992 colon cancer operation. His localized diagnosis and surgery-only treatment mark a similar pattern of papal recovery in the modern era.
For patients diagnosed with localized lung adenocarcinoma, this case illustrates that surgical removal of part of the lung can be followed by a return to normal daily activities. Readers facing a similar diagnosis should discuss recovery timelines and follow-up care with their own physicians.
The takeaway
Localized lung cancer detected early and treated surgically can allow a patient to return to daily life, but recovery pace varies, so following medical guidance on gradual resumption of activity remains important.
What happens next
Pope Leo's decision on whether to proceed with the planned November 6-17 trip to Uruguay, Argentina, and Peru is expected to determine his travel schedule for that period.
