Venezuela's Chavez to have cancer operation

CARACAS - Venezuelan President Hugo Chavez said on Saturday he would undergo another cancer operation in coming days after doctors found malignant cells during tests in Cuba.
"It is necessary for me to have a new intervention in the coming days," Chavez said in a televised broadcast, adding he would return to Havana on Sunday. The socialist leader had flown back to Venezuela on Friday after the tests in Cuba.
The 58-year-old president has already had three cancer operations in Cuba since the middle of last year. News of more surgery will likely raise new doubts about his political future and the fate of his self-styled "revolution" in the OPEC nation.
In his comments on Saturday, Chavez sat alongside members of his Cabinet, including Vice President Nicolas Maduro and Congress head Diosdado Cabello, two close and powerful allies who might look to replace him if Chavez were to leave office.
