One year on from the BBC's investigation into the death of 23-year-old Paloma Shemirani - and two years since it happened - this episode of Top Comment explores what the case tells us about the dangers of medical misinformation. Last June, Marianna revealed how Paloma’s brothers blamed their mother - the prominent anti-medicine conspiracy theorist Kate Shemirani - for Paloma’s decision to reject chemotherapy. She denies these allegations. Now, we speak to Paloma's twin brother Gabriel about the aftermath of the inquest, what he wants to change to protect people like his sister, and the evolution of unregulated health advice online.
