Venezuelan President Hugo Chavez is returning to Cuba for medical treatment.
Chavez disclosed his travel plans Tuesday in a letter to the country's National Assembly.
The president says doctors have recommended a special treatment known as hyperbaric oxygenation, which involves breathing pure oxygen in a sealed chamber.
The American Cancer Society says it can be used to prevent bone decay following radiation therapy.
Chavez says that treatment, combined with physical therapy, will consolidate the process of strengthening his health.
