WASHINGTON  Gen. David H. Petraeus, the commander of American military forces in the Middle East, received a diagnosis of early-stage prostate cancer in February but has undergone “successful” radiation treatment to deal with the illness, according to a statement issued late Monday.

General Petraeus, 56, who as head of the United States Central Command oversees operations in Afghanistan and Iraq, underwent two months of radiation treatment at Walter Reed Army Medical Center, which had “minimal impact on his work schedule,” according to the statement.
