Venezuelan President Hugo Chavez flew to Cuba early Sunday morning for another round of radiation treatment.
He was greeted at the Jose Marti International Airport, southwest of Havana, by Cuban leader Raul Castro with whom "he maintained a lively exchange," Cuba's state-run Juventud Rebelde newspaper said.
The 57-year-old president has not specified the type of cancer he is battling, and the government has released few specifics - fueling widespread speculation about his health and political future.
On Thursday, he returned home to Venezuela from a second round of treatment - and spent the weekend there.
So far this year, Chavez has spent 34 days in Havana.
Speaking at a Mass in his home state of Barinas on Thursday night, he teared up at times as he discussed his struggle with illness.
"Christ ... give me life, because I still have things to do for the people and this country. Do not take me yet," he said.
Chavez described cancer as "a true threat that marks the end of the path for many people. The end of the physical path, that's the truth."FULL STORY
