Bishop Carl Mengeling of Lansing is scheduled to undergo surgery today. He was diagnosed with bladder cancer and will have his bladder removed.

The 76-year-old bishop will take six to eight weeks to recuperate from the surgery. The faithful were asked to pray for their bishop at all weekend Masses.

"We know people have his best interests at heart, and cards and letters are gratefully received," said Michael Diebold, the diocese’s director of communications.
