Rome: Pope Leo XIV resumed his regular diet, began walking and celebrated Mass in the hospital Wednesday as he recovered from surgery to remove a cancerous mass from his lung, the Vatican said. Questions remained about whether the cancer had spread, while Peru's president suggested Leo might have to alter his planned visit to Latin America next month.
Blood tests and a chest X-ray showed the 71-year-old pope was recovering normally, his two doctors said.
"The Holy Father underwent respiratory physiotherapy and has begun walking in his room. He resumed his regular diet and had breakfast and lunch," said Dr. Luigi Carbone, the pope's personal doctor, and Dr. Stefano Margaritora, the head thoracic surgeon at Gemelli hospital. "Recovery is proceeding as planned."
Tuesday's surgery confirmed that Leo has lung adenocarcinoma, the most common type of lung cancer. Surgeons removed the lower lobe of his right lung.
The right lung has three lobes and the left has two. After one lobe is removed, the remaining lung tissue can gradually compensate, especially in otherwise healthy, physically active people. Leo is known for his interest in sports, including weekly tennis games and swimming.
The Vatican said late Wednesday that the pope had celebrated Mass with his secretaries in the afternoon in a special chapel set up for him on the 10th floor of the hospital.
No word yet on whether the pope's cancer had spread
Experts said some of Leo's lymph nodes would also have been removed and tested to determine whether the cancer had spread. Those results have not so far been made public.
If the cancer has spread, test results will guide treatment, said Dr. Stephen Liu, a lung cancer expert at Georgetown's Lombardi Comprehensive Cancer Center. Options include chemotherapy, a combination of chemotherapy and immunotherapy, or targeted therapy, which uses pills to treat cancers with specific characteristics.
Liu, who is not involved in the pope's care, said that, of the different types of lung cancers, adenocarcinoma has the most favorable prognosis.
"While we know the diagnosis, we now need to know the stage," Liu said. "We now need to know how big it is, how many spots in the lung are involved. Is it just one nodule, or more than one, and the lymph nodes, are they cancerous?"
Dr. PierCarlo Gentile, head of radiation oncology at Rome's San Pietro Fatebenefratelli Hospital, said the minimally invasive, video-assisted chest surgery the pope underwent typically requires 15 to 20 days of recovery. Postoperative complications, including infections, are rare, he said.
Doubts over Latin America trip
The Vatican hasn't announced any changes to Leo's planned trip to Uruguay, Argentina and Peru on Nov. 6-17.
But Peruvian President Keiko Fujimori said Wednesday that the pope's diagnosis and recovery could affect the visit, even as she expressed hope it would go ahead. Leo spent two decades as a missionary in Peru, holds Peruvian citizenship and is beloved by his flock there.
"We understand that this recovery will take several weeks, longer than expected," Fujimori told reporters. "We also understand that there could be some changes to the schedule of his visit."
The ambitious itinerary for the longest trip of his papacy covers just over 31,000 kilometers (19,000 miles), with a dozen flights and two helicopter rides across the three countries, as well as a significant change in altitude in Peru.
Fujimori said millions of Peruvians were praying for the pontiff's recovery and awaiting further announcements from the Vatican.
"We hope his recovery will be swift and that his visit can go ahead, but we will also understand if that is not possible," she said. "What matters most is that His Holiness regains his health."
Oncology surgeons often advise patients not to fly for three weeks after surgery.
"If it is Stage 1, he can complete these trips. If more treatment is needed, I would likely advise against the trips," said Liu.
Doctors took tissue samples before surgery
The pontiff has offered a rare degree of transparency about the first publicly disclosed major health problem of his 17-month papacy.
He revealed the discovery of a nodule, or growth, on his lung during his Sunday noon prayer, announcing it on live television. But Leo did not disclose everything he knew Sunday.
