Venezuelan President Hugo Chavez had surgery Tuesday to remove a lesion from his pelvis and is now in good physical condition after the operation, Reuters said.
Chavez, 57, had new surgery in Cuba despite insisting that he had been cured of cancer during previous operations in Havana last year.
This latest health setback has fueled fresh doubts about Chavez's health and the possibility of campaigning for re-election in October.
Doctors found a large cancerous tumor in Chavez's pelvis back in June, which is what sparked his need for the operation.
Chavez traveled to Cuba for treatment because the communist-led Caribbean island's former president, Fidel Castro, is a close friend and his main political mentor.
