Rare Contagious Cancer Found in Fish from Quebec and U. S. Lakes The discovery of contagious cancer among catfish in Quebec and U. S. lakes has left scientists and anglers perplexed.
A study published in Nature reveals that melanoma tumors are spreading from one fish to another, a phenomenon previously observed only in a handful of other species.
This finding is significant not just because it challenges our understanding of cancer but also because it highlights the intricate relationships between humans, animals, and their environment.
