Venezuela’s cancer-stricken President Hugo Chavez is still suffering from respiratory problems, and the evolution of that condition “has not been favorable,” the information minister said Thursday. Chavez, who returned home early Monday after a fourth cancer surgery and more than two months of convalescence in Cuba, will receive more treatment for the breathing issue, Ernesto Villegas said. “Medical treatment for the underlying condition (cancer) continues without present significant adverse effects so far,” he said in a statement read and broadcast on television and radio stations in the country. Chavez “remains in communication with other family members and the government’s political team, and is working in close collaboration with the medical team,” Villegas added.
