Lima: Former Peruvian president Alberto Fujimori`s chief doctor says he has been hospitalised for surgery to correct lesions on his tongue.
Dr Alejandro Aguinaga said that Fujimori entered a hospital on Sunday. It will be the fourth time since 1997 that he has undergone such an operation.
Aguinaga says the procedure is scheduled for Monday morning.
The 71-year-old former leader is serving a 25-year jail sentence for killings and kidnappings by security forces during his presidency.
Fujimori ruled Peru with an increasingly iron fist from 1990 until 2000, when his government collapsed amid a bribery scandal.
In 2005, he left exile in Japan and travelled to Chile, where he was arrested and extradited to Peru.
