Venezuela's vice president says Hugo Chavez's second cycle of radiation treatment was successful.

Elias Jaua says Chavez plans to return to Venezuela on Wednesday after receiving treatment in Cuba.

Chavez has vowed to beat cancer to win re-election in October.

Chavez has not identified the type of cancer he is trying to overcome.

The socialist leader has said he choose to undergo treatment in Cuba because it's where his cancer was originally diagnosed and where his surgeries have been carried out.

Chavez expects to be traveling to Cuba for treatment for several weeks.
