Pope Leo needs no more cancer treatment; Assisi trip cancelled, Nov trip on

Vatican doctors have concluded that Pope Leo XIV needs no further cancer treatment after tests on tissue removed during lung surgery confirmed the disease was localized. However, they advised him to cancel a planned trip to Assisi while he recovers, the Vatican announced on 22 October 2026.

Key facts

• 22 October 2026: the Vatican said no additional cancer therapy is needed
• 27 October 2026: the Pope's trip to Assisi has been cancelled
• 6 November 2026: an 11-day journey to Uruguay, Argentina and Peru is still scheduled
• Surgery took place on 13 October 2026 at Rome's Gemelli hospital
• The Pope was discharged on 17 October 2026, days earlier than first projected

What did the medical tests show?

Final examinations of tissue taken out during the operation confirmed the illness was localized lung adenocarcinoma, a cancer that develops in glandular cells. An oncological evaluation then determined that no further therapy was required, according to a Vatican communique.

The findings came just over a week after surgeons removed the lower lobe of the Pope's right lung on 13 October, following the detection of a suspicious growth that was later confirmed to be cancerous.

Which travel plans are affected?

The Vatican said Pope Leo will not travel to Assisi on 27 October for an interreligious peace gathering marking the 40th anniversary of the World Day of Prayer for Peace convened by St. John Paul II. A follow-up chest X-ray showed his recovery was progressing extremely well, but doctors advised against the planned helicopter journey given how recently he had surgery.

His departure on 6 November for an 11-day apostolic journey to Uruguay, Argentina and Peru remains on the schedule. Dr. Stefano Margaritora, the lead thoracic surgeon who operated on the Pope, told Vatican News on 17 October that he saw no medical obstacles to the trip. "There are no clinical reasons why it should not take place," he said of the air travel planned for the following weeks.

How has the recovery gone?

The Vatican issued daily updates during the Pope's hospital stay, reporting that recovery was progressing as expected and postoperative results were within the expected range. He began respiratory therapy, walked and resumed eating the day after surgery, and celebrated Mass with medical staff on 16 October.

He was discharged on 17 October, several days ahead of initial projections, and led the Sunday Angelus prayer at the Vatican on 18 October. Dr. Margaritora said the Pope could be fully recovered in about another 10 days.

What this means for travellers

Travellers planning to attend the interreligious gathering in Assisi on 27 October should note that the papal visit will not take place. Those expecting papal events in Uruguay, Argentina or Peru from 6 November can treat that journey as scheduled, though the source gives no further detail on the programme.

No further medical bulletins or changes to the November itinerary have been announced.
