Pope Leo XIV was admitted on Tuesday morning to the Gemelli hospital in Rome for surgery to remove a nodule in his lung, according to G1.

The Vatican did not say whether the nodule is malignant or benign, but said it is “well controlled and at an early stage”. Cardinal Piero Parolin said he is “worried” about the surgery “because no one expected something like this”, but that the pontiff is “serene”. The surgery was scheduled for 11 a.m. Brasília time, according to sources at the Holy See.
