Finding a cure for cancer is unarguably one of the biggest medical challenges that we face. But what if we could find a way to prevent cancer before it even starts?
In a special extended edition of their Big Questions Podcast, the Oxford Sparks team spoke to Professor Sarah Blagden, an experimental oncologist in the Department of Oncology, and Anna Fry, who has the cancer predisposing condition Lynch Syndrome - putting her at increased risk of developing colorectal and other cancers.
Sarah explains how clinical trials of vaccines targeting 'pre-cancer' could revolutionise the fight against cancer, beginning with those at greatest risk.
