Scientists identify fourth transmissible cancer, first in fish

Scientists have identified a new transmissible cancer in brown bullhead fish, marking the fourth known transmissible cancer and the first of its kind in fish and freshwater environments. This melanoma, first observed in Lake Memphremagog, spreads as living cancer cells and is not caused by a virus or bacteria, but rather by a contagious clone of cells. The cancer has a wide geographic distribution across North America, appearing in numerous states and Canadian provinces, though it is only abundant in a few specific locations. AI
