Venezuelan President Hugo Chavez announced Saturday that his cancer is back and he will undergo surgery in Cuba, CNN reported.
In a televised address, Chavez named Vice President Nicolas Maduro as his successor, should his health worsen. The admission was shocking to many, as this was the first time Chavez has spoken publicly of the possibility of a successor.
A special session of parliament will be convinced Sunday morning to discuss Chavez's health and his upcoming trip to Cuba.
Neither Chavez nor his Cuban doctors have ever disclosed what kind of cancer the president faces.
Recurring bouts of cancer have filled Chavez throughout the last few years of his presidency, requiring him to be treated for weeks at a time in Cuba.
Chavez was reelected in October for a fourth six-year term in office, the BBC reported.
