LOS ANGELES -- Actor Robert De Niro has been diagnosed with prostate cancer but is expected to recover fully, a spokesman said Monday.

Doctors for De Niro, 60, a two-time Academy Award winner, caught the cancer at an early stage during a regular health checkup within the past week, De Niro publicist Stan Rosenfield said.

De Niro is in otherwise excellent physical condition and doctors expect a full recovery, Rosenfield said.

The publicist said De Niro did not want to disclose if he would be undergoing surgery or some other treatment.

"He's a private person and doesn't care to have his treatment out for public consumption," Rosenfield said.

De Niro, nominated six times for Academy Awards, won the best-actor Oscar for 1980's "Raging Bull" and the supporting-actor honor for 1974's "The Godfather, Part II."
