MANILA - PHILIPPINES President Gloria Arroyo has undergone tests for cancer but doctors found no malignant growths, her spokesman said on Thursday.

Biopsies were carried out this week after a 'certain mass' was found in the 62 year-old grandmother's groin and breast, presidential spokesman Cerge Remonde told reporters.

'Indeed she is in top shape,' Mr Remonde said, declining to provide details.

Arroyo had checked into a Manila hospital early this week on her arrival from a Latin American tour as a precautionary self-quarantine measure against H1N1 flu, which has infected nearly 2,000 people in the Philippines.

It was understood that the biopsies were performed during her stay in hospital.

She was discharged late on Thursday and resumed her public functions on Friday, palace officials said. -- AFP
