LIMA, Sept. 5 (Xinhua) -- Former Peruvian President Alberto Fujimori was hospitalized on Friday at the National Institute of Neoplastic Diseases (INEN) for further tests after doctors detected a cyst in his pancreas.

    Doctors from the Abdomen Department at the INEN will perform hepatic and pancreatic function tests among others on Fujimori in order to confirm or dismiss the possibility of cancer, local media said, adding that the final results will come out Monday.

    According to INEN chief Cesar Vallejos, the former president, who was transferred in an ambulance to the INEN from his detention center amid heavy security, has a pancreatic cyst about 1.5 cm in diameter.

    This is the second time Fujimori has been tested at the INEN since June, when he had some tumorous tissue removed from under his tongue.

    Fujimori governed Peru from 1990 to 2000. He is still being tried on charges of ordering two massacres of insurgents in 1991 and 1992, in which 25 people were killed.

    He would face up to 30 years in prison if convicted.
