Level 3 CEO James Crowe has successfully undergone surgery, and a tumor was found to be benign, the company said today.

"Mr. Crowe has undergone his scheduled surgery, which was completed without complications," the Broomfield communications network operator said in a statement. "It is anticipated that Mr. Crowe will resume his work schedule following a two to three week recovery period."

The tumor of the pituitary gland was discovered by Crowe's doctor recently during a routine physical exam.
