Part 04 · The Genomic Power Shift
Genomics is already changing medicine, from rare disease diagnostics to cancer treatment, pharmacogenomics and newborn sequencing. This part explores how genetic information can help doctors understand disease, choose treatments and predict risk, while also raising difficult questions about privacy, consent, cost and responsibility.
The chapter connects genomic medicine with stem cells, lab-grown tissues, experimental animals and the long history of humans as research subjects. It also looks at genomics before birth, inherited disease, complex disease, infectious disease, parasites, viruses and precision medicine. Beyond the clinic, it explores how genomics enters everyday life through smell, diet, exercise, wellbeing, the microbiome, reproduction, evolution and the dream of living longer — perhaps even forever.
This is where the promise of genomic health meets its most uncomfortable questions: what should we know, what should we change, and who gets to decide?
