Chavez back in Venezuela

Venezuela's Hugo Chavez flew home on Friday after cancer surgery in Cuba, vowing to conquer the illness and win an October presidential election despite the need for radiation treatment.
"Who said the path was going to be easy?" said Chavez, 57, in an emotional speech to the nation on the runway. "I have promised I will live, and to this end I will give my all!"
The socialist president's return to Venezuelan soil after an absence of three weeks in Havana reasserts his leadership, calms anxiety among supporters and quells whispers of a succession struggle behind the scenes.
Yet little is known about what kind of cancer Chavez has or how serious it is. So big questions remain as to whether he is fit enough to campaign for an October 7 election that has turned into the biggest political fight of his 13-year rule.
