Venezuelan President Hugo Chavez is back in Cuba for more cancer treatment.

Mr. Chavez arrived in Havana late Saturday, where he was greeted by Cuban President Raul 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 Mr. Chavez needs a second round.

The 57 year-old Mr. Chavez has not said exactly what kind of cancer he has or to what extent it has spread.
