Venezuelan President Hugo Chavez is to undergo further treatment for cancer in Cuba, a month-and-a-half after achieving re-election on a term that is to end in 2019, dpa reported. Congress on Tuesday granted him the legally-required permission to travel. It was not immediately known when he would arrive in Cuba. In his formal request for permission to travel, Chavez explained that his doctors advised, six months after the latest radiotherapy session he underwent, "special treatment" including hyperbaric oxygen therapy. Chavez, 58, who has governed Venezuela since 1999, won the October 7 presidential election with 55 per cent of the vote and will start a further six-year mandate in January. He underwent surgery for an unspecified cancerous tumour in June 2011 in Cuba, and again in February.
