General David Petraeus, the top U.S. commander for the wars in Iraq and Afghanistan, has been treated for prostate cancer.

The 56-year-old general was diagnosed with prostate cancer in February, thought it was not publicly disclosed at the time at his request.
    
Petraeus underwent two months of radiation treatment at Walter Reed Army Medical Center in Washington.
     
The Pentagon said Petraeus' treatment was "successful" and did not interfere with his duties. Petraeus made at least one overseas trip during his treatment.
