Doctors have safely removed a bullet that had been lodged in a Vietnamese man's lung for nearly three decades, his surgeon said Monday. Doctors at Thanh Hoa hospital presented the bullet to Vu Van Thanh, 50, about two weeks ago. The 2.5-centimeter AR15 bullet had been stuck in his lung since he was shot while fighting in neighboring Cambodia in 1978. Thanh Hoa is 160 kilometers south of Hanoi. "I have never seen a case like this," said Dr. Nguyen Van Chung, who removed the bullet. "It's amazing that he didn't feel pain until recently."
