Our sister died because of our mum's cancer conspiracy theories, say brothers
Published: 6/23/2025

Brothers Gabriel and Sebastian Shemirani share how their sister's death at 23 was a result of their mother's anti-medicine conspiracy theories, which led their sister, Paloma, to refuse cancer treatment. Paloma tragically passed away after following alternative therapies promoted by their mother, Kate Shemirani, a former NHS nurse known for spreading Covid-19 misinformation. The brothers are now raising awareness to prevent similar tragedies and calling for social media platforms to take stronger action against medical misinformation, emphasizing the risks of such beliefs on vulnerable individuals.
