Evita, First Lady: A Biography of Eva Perón by John Barnes:
The crowd knew it. There were many men as well as women weeping openly in the plaza. One November 6, she was operated on for cancer of the uterus. Her newspaper, Democracia, said that before she went under the anaesthetic she cried, ‘Viva Perón!’ which must have shaken Dr. George T. Pack, the New York Memorial Hospital cancer specialist who performed the operation.
