What happened to Paloma? Aged 22, Paloma Shemirani has her whole life ahead of her. She’s recently graduated, moved into a flat and found a job. But just days before Christmas in 2023 she receives bad news, she has cancer - an aggressive but treatable form of Lymphoma. Despite a good prognosis, Paloma decides - at least initially - to reject chemotherapy. The BBC’s social media investigations correspondent Marianna Spring investigates what happened and what this tells us about the mainstreaming of anti-medicine ideas.
