De ce cancerul nu se transmite între oameni: Descoperirea făcută de cercetători după studierea unor cazuri extrem de rare

Cancer is a leading cause of illness and death worldwide, with rare cases of transmissible cancer observed in certain animal species. Recent research identified a new transmissible cancer in freshwater catfish, marking only the fourth known instance in nature. Unlike cancers caused by infectious agents, these cancers involve the transfer of cancer cells between individuals. The mechanisms of transmission vary among species, with factors like genetic diversity and immune response playing crucial roles. While no evidence suggests transmissible cancer exists in humans, studying these cases in animals may provide insights into cancer biology and immune evasion.
