Genome sequencing can provide the key to cancer prevention

A genome is the body's instruction manual. It's made of DNA and there is a copy in almost every cell. Through genome sequencing and genomics, clinicians can better understand how cancer cells might evolve and what treatments will be most responsive, known as precision and personalised medicine. Furthermore, genomics combined with technologies such as machine-learning and artificial intelligence (AI) has huge, as yet untapped, potential for determining a healthy person's future risk of cancer. To sequence the first genome cost $3 billion and took 13 years.
