Pope Leo XIV will not require any further cancer treatment following surgery to remove a tumour from his lung, his medical team has confirmed, offering reassurance about the 71-year-old pontiff's health less than two weeks after the procedure.
The pope's personal physician, Dr Luigi Carbone, and the head of his surgical team, Professor Stefano Margaritora, released a joint statement on Wednesday confirming the results of final post-operative testing. The statement revealed the tumour was a pulmonary adenocarcinoma, the most common form of lung cancer, and that the disease had been entirely localised. A further evaluation, the pair said, confirmed that no further treatment is necessary.
Surgery found to be sufficient as cancer had not spread
Leo underwent the operation last week, during which the lower lobe of his right lung was removed in an effort to ensure all cancerous tissue was excised. The procedure marked the first significant health event of his 17-month pontificate.
Post-operative testing is standard practice in such cases. Additional treatment, such as chemotherapy or radiation, is typically offered only when follow-up results indicate the cancer has spread, for example through the lymph nodes, or shows signs of being particularly aggressive. In this instance, the results indicated neither was the case.
A lung cancer specialist at Georgetown's Lombardi Comprehensive Cancer Center, Dr Stephen Liu, commented on the outcome, saying the statements pointed to a stage one lung cancer diagnosis. "Surgery is highly effective and expected to be curative," he said, adding that the decision not to pursue further treatment suggested a relatively small tumour that had not reached the lymph nodes.
Pulmonary adenocarcinoma accounts for roughly 40 to 50 per cent of all lung cancer cases. While the condition is strongly associated with tobacco use, it also occurs in non-smokers, a category that includes Pope Leo.
Professor Margaritora told Vatican News that the nodule had been discovered by chance during routine abdominal examinations, and that the pope had not been experiencing any symptoms at the time. It appears to have been what doctors call an incidental finding, where a scan conducted for an unrelated reason picks up an abnormality before it has grown large enough to cause any obvious health issues. Such early detection frequently means surgery alone is sufficient treatment.
Pope made unusually transparent disclosure about his diagnosis
The pope broke with a long tradition of Vatican secrecy around papal health matters when he publicly disclosed during his traditional Sunday blessing on October 11 that a nodule would be surgically removed. The announcement was broadcast live on television and drew widespread attention for its openness.
The initial diagnosis prompted expressions of concern and goodwill from around the world. Australian Prime Minister Anthony Albanese was among those who responded publicly. "Pope Leo XIV is a source of inspiration to Catholics right around the world, and here in Australia," he said, describing the pontiff as "a voice for peace, humanity and reason in our modern world" and offering his prayers for a full recovery.
Leo was discharged from Rome's Gemelli Polyclinic on Saturday, just four days after surgery, and indicated he would gradually return to his regular duties. Since leaving hospital he has already made two public appearances at the Vatican. The first was the traditional Sunday blessing from a window overlooking St Peter's Square. The second was a longer general audience in the square itself on Wednesday, where he told those gathered: "Thank you! Thank you for the support of your prayers."
While hospitalised, the pope also remained engaged in global affairs, including a phone call with Russian President Vladimir Putin.
South America tour still on the agenda despite recovery
Pope Leo's next major commitment is an ambitious international trip to Uruguay, Argentina and Peru, scheduled to run from November 6 to 17. The itinerary is demanding, involving more than a dozen flights, two helicopter journeys and stops at high altitude.
Professor Margaritora stated there were "no clinical reasons" that would prevent the pope from undertaking the journey. However, the Vatican's secretary of state has indicated the pontiff may need to adjust the pace of his schedule to support his ongoing recovery.
The pope himself has expressed a clear desire to proceed with the trip as planned. His strong public appearances this week appear to have reinforced the medical team's confidence in his progress.
The transparency surrounding Leo's diagnosis and recovery has been widely noted as a departure from the historically guarded approach the Vatican has taken to papal health. For many observers, the swift confirmation that the cancer was caught early and treated successfully will come as a significant relief.
