BOGOTA, Colombia (AP) " Colombian President Juan Manuel Santos says he'll undergo radiation to treat high levels of a prostate-specific antigen, though his doctors say that doesn't represent a return of cancer.
Santos' doctors delivered their prognosis Monday based on tests last week at Johns Hopkins Medicine in Baltimore.
The doctors assure that there's no indication that a tumor removed in 2012 had returned. Still, they're closely monitoring what they described as a barely detectable but abnormally high level of the antigen.
They say this year's Nobel Peace Prize winner will have to take a non-hormonal and non-chemotherapy drug whose possible side effects will be managed through a single session of radiation.
His doctors say the radiation won't affect his activities and described the president's overall health as good.
