(CNN) — Venezuelan President Hugo Chavez, who had surgery in 2011 to remove a cancerous tumor, announced late Saturday that he will undergo a new operation after doctors recently detected malignant cells.
Just this week, the president returned from Cuba after receiving medical treatment. Chavez said he will return there Sunday and that the expected operation will occur in coming days.
Chavez has repeatedly spoken publicly about his cancer battle, but has never specified what type he has.
The president made the announcement during a televised address from the presidential palace
