FILE - In this Dec. 10, 2012 file photo released by Cuba's state newspaper Granma, Cuba's President Raul Castro, right, receives Venezuela's President Hugo Chavez at the Jose Marti International airport in Havana, Cuba. Chavez arrived in Cuba on Dec. 10, 2012 for a fourth cancer-related operation after designating Vice President Nicolas Maduro as his political heir. The long and at times surreal saga surrounding the cancer treatment of President Hugo Chavez has many Venezuelan writers and intellectuals likening the nation's drama to a telenovela. Venezuela has long produced soap operas, and some say no one could have imagined a more bizarre plot than the one unfolding in the more than seven weeks since Chavez traveled to Cuba for his operation and disappeared from public view.
