Venezuelan President Hugo Chavez, 57, underwent an operation in Cuba on 20 June to remove a cancerous tumor in his pelvic area. After a brief return to Caracas, he travelled back to Havana on 16 July for a week to undergo his first chemotherapy treatment.
Chavez returned to Cuba again for more treatment on 6 August.
On Thursday, the Venezuelan leader said his second round of chemotherapy was going well and he will "win the battle" against cancer. "God willing, everything will end well," Chavez said in a telephone interview with Venezuelan state television network VTV. "This is a battle we are winning, and that we will win."
Cuban President Raul Castro accompanied his Venezuelan counterpart to the airport late Saturday to see him off, Juventud Rebelde newspaper reported Sunday.
