Pope Leo XIV's doctors say no further treatment is needed after lung cancer surgery

Doctors for Pope Leo XIV said in a Vatican statement that no further treatment is necessary following the surgery he underwent for lung cancer. The conclusion was reported on October 21, 2026.

The tumor was removed on October 13, 2026. The doctors confirmed that it was lung adenocarcinoma, a type of lung cancer, and that the disease was localized, meaning it was confined to one area. NBC News reported the doctors' conclusion in these terms: "no further therapy is required."

The assessment rests on final tissue and molecular tests. Tissue tests examine a sample of the tumor under a microscope, and molecular tests look at the genetic features of the cancer cells. According to the doctors, both sets of results confirmed that the cancer was localized.

Vatican News and ABC News carried the same finding: the pontiff's doctors do not consider further treatment necessary.

The statement sets out the doctors' view of the cancer's stage and the course of care.
