Researchers say this is the first documented case of someone dying from cancer caused by parasitic cells.By Ryan Biek | November 5, 2015
In the first case of its kind, a man has died from cancer not caused by his own cells, but from those of a parasite.
In 2013, a 41-year-old Colombian man went to a hospital with trouble breathing and a fever. He'd also stopped taking his HIV medication months before, which weakened his immune system.
Upon examining him, doctors discovered his lungs were filled with tumors. A Centers for Disease Control and Prevention pathologist told NPR, "It looked like cancer, but the tumors were composed of cells that were not human."
