Pope Leo XIV was admitted to Rome’s Gemelli Hospital on Oct. 13 for surgery to remove a lung nodule that afternoon. [S3][S4]

Verification result: verified, because four independent reporting families directly support his admission for the planned lung operation and no validated contradiction challenges that account. [S1][S2][S3][S4]

The strongest evidence is ABC News’s direct quotation of the Vatican press office confirming both the admission and the scheduled procedure. [S3]

Pope Leo had announced on Oct. 11 that doctors found the nodule and that he would undergo surgery. [S3][S4]

OSV reports that he arrived by car at about 1 p.m. Rome time on Oct. 13. [S4]

His hospital recovery was expected to last about one week. [S3][S4]

The Vatican canceled his scheduled audiences through Oct. 20. [S1][S4]

The supplied reports present no material inconsistency about the admission or planned surgery. [S1][S3][S4]

The characterization that the operation was low risk and would determine malignancy appears only in The Guardian among the supplied sources, so that detail remains independently unresolved. [S1][S3][S4]

The supplied material does not confirm completion of the operation or provide a postoperative outcome. [S1][S3][S4]
