NEW YORK (AP) — Placido Domingo underwent surgery last week to remove a cancerous polyp from his colon and is expected to make a full recovery, his spokeswoman said Monday.

The 69-year-old Spanish tenor had surgery last week at Mount Sinai Hospital in New York and was released Sunday, spokeswoman Nancy Seltzer said.

The malignancy was localised, and the operation was laparoscopic, a minimally invasive procedure in which a small incision is made in the abdomen, Seltzer said. Doctors have ordered Domingo to rest for six weeks, Seltzer said in a statement.

It's anticipated that he'll return April 16 with a performance of Verdi's "Simon Boccanegra" at Milan's Teatro alla Scala, she said. "His exact return to his performing engagements remains subject to how fast he can heal and regain his characteristic strength," she said.

In addition to singing and conducting, Domingo will continue as general director of the Los Angeles Opera and the Washington National Opera.

After completing a run of "Simon Boccanegra" at New York's Metropolitan Opera on Feb. 6, where he took on a rare baritone role, Domingo travelled to Japan and felt abdominal pain during performances in Tokyo in Feb. 13-14, Seltzer said. He then returned to New York for surgery.

Considered among the most accomplished tenors, Domingo has sung 130 roles. He is scheduled to sing Pablo Neruda in the world premiere of Daniel Catan's "Il Postino" at the Los Angeles Opera on September 23.

While he will miss singing Boccanegra at the Zurich Opera on March 23, his performances of the Verdi tile role remain scheduled in Milan, at London's Royal Opera opening June 29, and at Madrid's Teatro Real starting July 22.
