Hugo Chavez, the Venezuelan president, has returned to Caracas after 11 days of cancer treatment in Cuba, state television and officials say.
Chavez was seen chatting with his vice-president and other aides after arriving in the Venezuelan capital early on Thursday.
The popular president, who seeks to run for re-election for a six-year presidential term in October, has been undergoing radiation treatments in Cuba since late March. He was operated on in February to remove a second tumour from his pelvic region.
The first tumour was taken out in June last year, and he then underwent chemotherapy.
Chavez has kept secret some details of his illness, including the type of cancer and the precise location of the tumours.
On Tuesday, he appeared on Venezuelan state television for the first time in 10 days - since his latest round of cancer treatment began - depicting relative good health and indicating that he remains vigorous despite his cancer treatment in Cuba.
