Former president Alberto Fujimori, serving 25 prison for human rights abuses, was moved to a hospital specializing in cancer treatment after his health deteriorated.
Fujimori was president from 1990-2000. In April 2009, he was convicted of crimes in connection with a army death squad that operated during his rule.
His 35-year-old daughter Keiko, a likely candidate for the presidency in 2011, has vowed to pardon her father.
