Pope Leo XIV does not require any further treatment following surgery to remove a cancerous growth from his lung, the Vatican has confirmed.

Test results on tissue removed during the operation confirmed a diagnosis of lung adenocarcinoma. Both tissue and molecular tests established that the disease was localised.

"A subsequent oncological assessment has confirmed that no further treatment is necessary," the Vatican said in a statement.

The 71-year-old pontiff underwent the procedure on 13 October. The surgery lasted 90 minutes and included the removal of the lower lobe of his right lung.

Pope Leo XIV himself had announced the operation during his weekly Sunday prayers at St Peter's Square, telling those gathered that doctors had found a nodule on his lung. He said at the time that it had been caught "at an early stage."

He was discharged from Rome's Gemelli Hospital over the weekend, four days after the operation, stopping to speak to well-wishers as he left the grounds.

Images shared on the Friday following his surgery showed the Pope celebrating Mass from the hospital, wearing green vestments and standing behind a makeshift altar.

On the same day, the Vatican said he spoke by phone with Russian President Vladimir Putin to urge a ceasefire in the blockaded Russian-occupied Ukrainian city of Oleshky, to allow the delivery of food aid, and to call for "dialogue and peace."

He held a similar phone call with Ukrainian President Volodymyr Zelensky on Monday.

Pope Leo XIV held his first weekly general audience since leaving hospital at St Peter's Square on Wednesday.

Those close to the Pope have said he was keen not to delay a planned trip to Latin America, scheduled for early November.
