(CNN) -- Venezuelan President Hugo Chavez said Saturday that he is headed back to Cuba for his fourth -- and possibly final -- round of chemotherapy, state news reported.
Chavez announced in June that doctors in Cuba had removed a cancerous tumor from his body, but he has not said what type of cancer he has. The president has undergone treatments in both Venezuela and Cuba.
"Early tomorrow I will start the fourth round of chemotherapy. The most likely scenario is that this (round) will be the last," Chavez said, according to the state-run broadcaster VTV.
The president spoke the same day he met with Bolivian President Evo Morales, who is expected to travel with Chavez to Cuba, VTV reported.
Chavez has pledged to run for re-election next year, dismissing speculation that his illness would force him out of politics.
