Scientists Aim to Beat Cancer Before Birth: Screening Embryos for Genetic Diseases

The video discusses the use of test tube techniques to screen embryos for genetic diseases, initially for conditions like cystic fibrosis. It highlights the case of Zain Hashmi, whose parents sought legal permission to have a child who could be a donor for their sick son. The video explains the process of screening embryos for inherited bowel tumors, ensuring only those without the cancer gene are implanted. Ethical concerns are raised by individuals like Emma Stevenson, who questions the morality of such decisions. Scientists aim to extend this technique to other genetic diseases, potentially preventing them from being passed down generations.
