ItalyResearchers from the University of Vermont have discovered a contagious tumor in freshwater fish that behaves like an infectious disease or parasite, challenging existing understanding of cancer origins. This tumor does not arise from internal genetic mutations but spreads between individuals, marking the first known instance of transmissible tumors in fish. The study, published in the prestigious journal Nature, suggests this phenomenon could reshape knowledge about the development and spread of cancers. The discovery highlights a rare biological mechanism where cancer cells can act as pathogens, infecting new hosts.
