Why are tumours more likely to develop in some tissues than others? Why are bowel and breast cancers so common when heart cancer is so rare? And will low doses of radiation from medical scans create the conditions for unruly cells to grow, even without damaging DNA? In the latest episode of Genetics Unzipped we’re tackling the Big Questions about the Big C as we dig into some of the mysteries surrounding what’s often seen as the ultimate genetic disease: cancer.Genetics Unzipped is written and presented by Kat Arney, and produced by First Create the Media for the Genetics Society - one of the oldest learned societies in the world dedicated to supporting and promoting the research, teaching and application of genetics. Production by Hannah Varrall.Full show notes, music credits and references online at GeneticsUnzipped.com
