Influencer Sidney Raz opened up about his own health journey after his unborn daughter died in utero.
Raz (real name Sidney Raskind) uploaded an Instagram video in April 2025 revealing that he and his wife, Kelsey, underwent genetic testing after losing their baby to a rare birth defect called holoprosencephaly in September 2024.
“It was found that [my daughter] had a deletion,” he said in the video. “So we did genetic testing on me and Kelsey didn’t have that deletion, but I did have that deletion. And because of that deletion, in recent years, it has been seen to cause certain types of cancer, specifically stomach cancer.”
He added: “I scheduled an endoscopy and … today I found out that I have stomach cancer.”
