As a result, the patients who received his liver, pancreas, and kidneys also developed the same cancer.

Two of them died, while the kidney recipients are currently undergoing treatment for the disease.

Meanwhile, the family of Tony Grier—a transplant recipient who died after receiving a cancerous lung—suing the Hospital of the University of Pennsylvania and the doctors who performed the transplant. His family claims that hospital officials told Grier he was getting the healthy lungs of an 18-year-old (a claim that the hospital denies) while in fact, the lungs came from a 31-year-old woman who smoked heavily and may have had a history of illegal drug use.

Although the radiation shattered their genomes—it was a far higher dose than had ever been tolerated by an animal to date—the plucky, resourceful gals sewed their chromosomes back together and not only survived the blasts but continued to reproduce.
