Pope Leo was diagnosed with lung cancer on Tuesday after doctors removed the lower lobe of his right lung, according to the Vatican. [S1][S2][S4][S5]

An intraoperative examination confirmed lung adenocarcinoma, which preoperative tests had suspected. [S1][S2][S3][S5]

The operation lasted approximately 90 minutes and was reported successful without complications. [S1][S2][S3]

Two days earlier, Leo had said doctors found a very early-stage, well-localized lung nodule and advised surgery. [S1][S5]

Verification result: verified, because four independent reporting families directly support the central claim and none of the material claims is contradicted in the supplied evidence. [S1][S2][S4][S5]

The supplied reports do not establish the pope's prognosis or whether further treatment will be required. [S1][S3]
