Haiti ? President Rene Preval, who was diagnosed with prostate cancer five years ago, said Sunday the disease may have come back and that he soon would leave the country for treatment and more tests.

Speaking to reporters after returning from a four-day trip to Cuba for medical exams, a fit-looking Preval said blood tests in Havana showed possible signs of cancer.

Preval said the tests were inconclusive and that he would have to return to Cuba on Dec. 26 for more tests and unspecified treatment. He did not say how long he would be out of the country.

“They (doctors) are unable to say right now at what stage this is,” Preval said after arriving at Haiti’s international airport. “I have to go back for more tests. If it continues to grow, that will mean the cancer came back.”

“The seriousness of it is not known,” Preval added, saying he felt “physically and mentally well.”

Preval, 63, was first diagnosed with prostate cancer in 2001, the last year of his first presidential term, and had surgery in Cuba to treat it.
