A scary fact is that one in two of us will get cancer, its a disease that touches every family in Britain. BBC’s Panorama has spent the last eighteen months on the frontline in the fight against the disease. At the Royal Marsden Hospital in London, patients that have been given just months to live are keeping cancer at bay for years. Advances in genetics are delivering a new generation of smarter cancer drugs. Leading scientists at the institute of cancer research see this as a game changing moment as patents that have run out of options under conventional treatment are helping to revolutionise our understanding of cancer.

In this episode of Panorama they meet up with the patients that are at the heart of clinical trials which promise a new armoury of weapons in the battle against cancer.
