OAKBROOK TERRACE, Ill. (CBS) — Cardinal Francis George said Friday he is still formulating a plan with his physicians to treat his latest cancer diagnosis and, as a man of faith, has mixed feelings about what the future may hold.

“We all live with the Lord as much as possible. If this is a call to be with Him for eternity, then that’s a welcome call in that sense. But it’s also a fearful call, because there’s so much that’s unknown,” George told reporters in west suburban Oakbrook Terrace, where he was appearing at a church event.

The cardinal’s remarks to reporters were his first public statements since the Archdiocese of Chicago disclosed last week that George, a bladder cancer survivor, has a new health crisis.

The diocese said doctors had discovered cancer cells in George’s kidney and in a nodule from his liver. The cardinal’s bladder was removed in 2006 and he had appeared cancer-free since then. It’s not clear if the latest cancer is related, he said.

“I felt I’d licked something, and I didn’t,” George said, smiling. “That isn’t a good feeling.”

The cardinal said he’s waiting on additional tests — expected next week — to determine a treatment regimen. He said he plans to maintain an active public schedule.

George, 75, had already tendered his resignation to the Vatican but wasn’t expected to retire for a couple of years.

“I was kind of looking forward to being able to do that,” he said.
