NEW YORK (AP) - CNN's Anderson Cooper was back at work Wednesday after minor surgery two days earlier to remove a cancerous mole from underneath his left eye.

There was no indication the skin cancer had spread, spokeswoman Shimrit Sheetrit said.

He blogged about his procedure Wednesday, when he was following Barack Obama, who is seeking the Democratic presidential nomination, for a special edition of Cooper's nightly news show.

"I hadn't planned on mentioning this," said Cooper, 40. "But I still have stitches and you'll no doubt notice them. ... Don't want you to think I got into a fistfight with Charlie Rose."
