Venezuelan Leader Prays for Life Before Cancer Treatment

Venezuelan President Hugo Chavez says he's heading back to Cuba late Saturday for a third round of radiation therapy as part of his cancer treatment.

Little is known about the 57-year-old socialist leader’s condition, including what type of cancer he has. Mr. Chavez has undergone three operations in less than a year, and received two sessions of radiation treatment.

He says the latest surgery was successful, and that he will be fit to win a new six-year term in October. On Thursday, a day after returning from Cuba, Mr. Chavez became emotional during a Mass held in his home state of Barinas.

Flanked by family members, Mr. Chavez asked God: "Please don't take me yet." In a breaking voice, he said he still has "things to do for my people and my country."

Mr. Chavez underwent an operation in February in Cuba to remove a tumor from his pelvic region. A tumor was extracted from the same area last year. He has also undergone two rounds of radiation therapy.
