A spokesman for Petraeus says the general was diagnosed with early-stage prostate cancer in February. Petraeus underwent two months of radiation treatment at Walter Reed Army Medical Center in Washington, and the treatment was successful.
The spokesman, Col. Erik Gunhus, says the treatment had little effect on Petraeus' job because he was in Washington for policy reviews and other Pentagon matters. Petraeus did make at least one overseas trip during his treatment.
President Barack Obama, Defense Secretary Robert Gates and other administration officials were informed of the general's diagnosis and treatment.
