Venezuelan President Hugo Chávez is back in Cuba for more cancer treatment.
Chávez arrived in Havana late Saturday, where he was greeted by Cuban President Raúl Castro.
Cuban doctors removed a large tumor from the Venezuelan president in June. The operation was followed by one round of chemotherapy last month. Doctors will run tests to determine if Chávez needs a second round.
The 57 year-old Chávez has not said exactly what kind of cancer he has or to what extent it has spread.
