The Vatican press office said the 71-year-old pontiff would leave the hospital in the early afternoon and return to the Vatican. It also said he is expected to lead the Angelus prayer from the window of the papal apartment tomorrow, a public reappearance that carries its own message of continuity after a week defined by surgery and medical bulletins.
The news is plainly encouraging, but it is still hospital-discharge news: a sign that doctors consider him fit to leave, not a rewriting of what brought him there. The Vatican has said a cancerous growth was removed from his lung and that the lower lobe of the right lung was taken out during the procedure.
Earlier in the week, the Vatican said pre-operative suspicions of pulmonary adenocarcinoma had been confirmed. It also said the surgery was successful and that there were no complications. According to the same account, the pope was in the operating room for about three hours, with the operation itself lasting around 90 minutes.
Leo has been recovering at Gemelli since the operation. On Thursday, doctors said a chest X-ray showed “good recovery” of the affected lung.
For now, the Vatican is releasing tightly bounded facts rather than a sweeping medical narrative: surgery, recovery, test results, discharge. That restraint is noticeable in a case where the symbolism of a pope back at his window can easily outrun the clinical detail.
