Social Media Influencer Sidney Raz Reveals Stomach Cancer Diagnosis Following Genetic Testing
Popular social media personality Sidney Raz, known for his engaging content and life-hack videos, recently shared his personal health update, disclosing a stomach cancer diagnosis. This revelation comes after Raz and his wife, Kelsey, underwent genetic testing following the loss of their unborn daughter in September 2024 due to a rare congenital condition called holoprosencephaly. The influencer, whose real name is Sidney Raskind, explained in an emotional Instagram video posted in April 2025 that the genetic screening identified a deletion in his DNA, which has been linked to an increased risk of certain cancers, including stomach cancer. Further medical examination, including an endoscopy, confirmed the diagnosis, marking the beginning of Raz’s public health journey.
