What are cancer patients seeing on social media? The BBC’s social media investigations correspondent Marianna Spring goes down the cancer conspiracy rabbit hole to find out. She returns to the days Paloma spent in hospital after her cancer diagnosis to analyse the advice Paloma was being given by medical staff versus the advice she was receiving from alternative practioners and her Mum, Kate Shemirani. Marianna investigates Paloma’s mum’s platform as a conspiracy theory influencer and looks at the wider role some social media sites are playing in turbocharging accounts that promote health misinformation. Plus, she speaks to the Vice President of Royal College of Radiologists to understand how harmful content on social media is affecting patients.
