The Hidden Science Behind Genetics, Immunity & the Fight Against Cancer

In this profound episode of Tomorrow Today, Shekhar Natarajan speaks with Sir Walter Bodmer, one of the world’s leading geneticists and cancer researchers, whose pioneering work has shaped modern genetics, immunogenetics, cancer research, and public understanding of science. Sir Walter shares his extraordinary journey from fleeing Nazi Germany as a child in 1938 to studying mathematics at Cambridge under Sir Ronald Fisher and later working alongside influential scientists including Jim Watson and Joshua Lederberg. The conversation explores the fundamental nature of cancer as a genetic and evolutionary disease, explaining what happens within cells as cancer develops and why understanding the human genome has become so important to modern medicine. Sir Walter also discusses the future of immunotherapy, early detection, targeted prevention, and personalized medicine, offering insights into how strengthening our understanding of genetics and the immune system could transform the way we prevent and treat cancer. The episode also explores population genetics, the Human Genome Project, interdisciplinary education, and the unique academic environment of Oxford and Cambridge. This is a fascinating conversation for anyone interested in genetics, cancer research, immunology, medicine, science, the human genome, and the future of healthcare.
