The Archdiocese of Chicago says Cardinal Francis George will undergo additional tests this week after doctors found cancerous cells in his kidney and liver.
The archdiocese gave an update Monday on George's condition saying the 75-year-old cardinal rested over the weekend and was "actively engaged" in his administrative responsibilities. Officials say that this week the cardinal will have more tests, participate in his annual retreat and keep previously scheduled public commitments.
George is the spiritual leader of 2 million Roman Catholics in the Chicago area. He survived bladder cancer six years ago. The archdiocese announced his latest diagnosis Friday after he underwent testing at Loyola University Medical Center.
The archdiocese said it would release more information about the cardinal's public schedule after he meets with doctors about courses of treatment.
Cardinal George underwent a complete medical checkup at the Mayo Clinic earlier this year and a spokesman said at the time that “he’s delighted with a good report.”
The Cardinal submitted a letter of resignation to Pope Benedict XV this year, a formality when Catholic bishops turn 75, but it wasn't accepted. He is expected to remain the head of the Chicago Archdiocese for two or three years.
