(CNN) - Gen. David Petraeus, the top U.S. military commander in the Middle East, has been treated for early stage prostate cancer and says recent screening tests have delivered "very positive" news.
He was diagnosed in February, his office said, and underwent two months of radiation treatment at Walter Reed Army Medical Center in Washington, D.C.
"My cancer was caught very early," Petraeus, 56, said in remarks released by his office. "I've had two PSA tests since completing treatment five months ago, and they've both been very positive. Surgery to remove the prostate was not an option due to plates/screws that were used to repair my pelvis after it was fractured in a parachuting accident."
PSA tests are blood tests performed to screen for prostate-specific antigens - proteins produced by cells of the prostate. Higher levels of PSAs could signal prostate cancer or benign prostate conditions.
At an appearance Tuesday after news of the treatment was out, Petraeus made only a lighthearted comment about this health.
