Venezuelan President Hugo Chavez's condition is improving after his latest surgery in Cuba, says Vice President Nicolas Maduro in a televised address.
Tuesday's surgery in Havana was the leader's fourth operation since mid-2011 for cancer in his pelvic region.
In a strong showing of support, over 3,000 of the country's top military and government officials attended a mass in Caracas on Thursday.
And a vigil was held in Havana.
Chavez credits Cuban leader Fidel Castro with saving his life, saying it was he who noticed his ill health and urged him visit a doctor.
Since then, the 58-year old South American leader has sought treatment in Cuba.
In a state TV campaign Venezuelan officials are cautiously preparing people for the possibility that Chavez may not survive.
One spot opens with Chavez's voice thundering "I am no longer myself, I am the people," followed by Venezuelans of all ages telling the camera: "I am Chavez."
Chavez's health has deteriorated dramatically since he won re-election two months ago.
