Scientists have developed a novel cancer treatment that disguises tumors to resemble pig organs, prompting the human immune system to attack them. This innovative method could halt or eliminate tumor growth, as shown in initial trials with monkeys and humans. The technique involves combining lessons from transplant medicine with oncolytic virotherapy, using the Newcastle disease virus engineered with a specific enzyme to trigger an immune response. While initial results show promise, further testing is necessary to fully understand its efficacy.
