Cancer epigenetics

What do they find, and can it change things? I'm your host, Chris Coates, and in this episode we're looking at research using Understanding Society's biological data, which examined how some genes work differently in different people.

I'm joined by Leo Sheltwick, an Emeritus Professor in the School of Life Sciences at the University of Essex, and Radu Zabet, a reader in AI and Cancer Epigenetics at Queen Mary University of London.

So Leo, could you start for us and just tell us to begin with what is epigenetics?

Well, the human body has about 10 trillion cells.
