CARACAS, Venezuela — Venezuelan President Hugo Chavez announced plans to travel to Cuba as early as Tuesday for more medical treatment after spending much of the past 18 months fighting cancer.
In a written request to the legislature, Chavez said doctors have recommended he “begin special treatment consisting of various sessions of hyperbaric oxygenation” and physical therapy to continue “consolidating the process of strengthening health.”
The request did not provide more details about the treatment or Chavez’s condition and was promptly approved by allied lawmakers at a special session in the city of Maracay. National Assembly President Diosdado Cabello read the request on television.
It said Chavez would travel to Cuba as soon as Tuesday. It did not say how long he will stay, though it said he would be back by Jan. 10, when he is being sworn in for a fourth term. Venezuelan law requires presidents to receive legislative approval before leaving the country for extended periods.
The treatment that Chavez is to undergo generally involves breathing pure oxygen while in a pressurized, sealed chamber. Its value is well-established for treating burns, carbon monoxide poisoning and some other medical conditions, and to aid wound healing and help repair bone and tissue damaged by radiation treatments.
However, the American Cancer Society says there is no evidence the treatment can cure cancer.
Hyperbaric oxygen treatment is employed by doctors in Cuba for the rehabilitation of patients with chronic illnesses, said Jesus Pena, a Venezuelan internist with a private practice in Caracas. But Pena said the announcement after a period of silence about Chavez’s condition raises suspicions about the reasons behind the treatment.
Opposition lawmaker Alfonso Marquina expressed concern about what he said seems to be a “veiled or deliberate attempt to continue creating uncertainty.”
Marquina told The Associated Press in a phone interview that if Chavez is traveling to Cuba for normal medical treatment as his request says, “the correct thing to do would be for a much more precise medical report to be given, and to not continue on with this sort of permanent uncertainty.”
The 58-year-old president first underwent cancer treatment in Cuba in June 2011 and suffered a relapse in February. He has since said he’s recovered from the pelvic cancer and won re-election in October.
Throughout his previous chemotherapy and radiation treatments, Chavez kept many details of his illness secret, including the type of cancer and the precise location of the tumors.
Chavez last appeared publicly during a televised meeting on Nov. 15, prompting some critics to publicly wonder where he went after his election win.
Opposition newspaper editor Teodoro Petkoff published an editorial in the daily Tal Cual on Tuesday before Chavez’s announcement, criticizing the president’s long absence.
Under the headline “The invisible man,” Petkoff said: “The health of those who govern can’t be a secret.”
