Placido Domingo had a cancerous polyp removed on March 2. ((

Tenor Placido Domingo made a triumphant return to the stage Friday night, performing for the first time after colon cancer surgery.

"It was a great evening," the Spanish singer said after appearing at the famed La Scala opera house in Milan, Italy, in Verdi's Simon Boccanegra.

"It was very emotional. I was happy to be in front of an audience."

Although there were a couple of boos, the tenor got a warm 14-minute ovation from the notoriously critical La Scala audience.

"There is a fantastic audience that feels great passion. You heard a generally enthusiastic audience," Domingo noted.

Surgeons in New York City removed a cancerous polyp from the colon of the 69-year-old only six weeks ago.

Domingo had admitted that he had put off his annual colonoscopy for years but then succumbed to intense pain after concerts in Japan in February.

"My biggest triumph ever is the one over illness," he declared earlier this week.

The tenor is slated for another six performances of Simon Boccanegra at La Scala, before taking the production to London's Royal Opera in June and Madrid's Teatro Real in July.

In September, he's taking on the role of the poet Pablo Neruda in the world premiere of Il Postino in Los Angeles.
