Sydney Towle has died at age 26. Her family confirmed the news on August 6, ending a three-year public battle with cholangiocarcinoma, a rare form of bile duct cancer. Towle gained a following of over 1 million people on social media by documenting her medical treatments and daily life.
Throughout her illness, Towle sought experimental medical options. In June 2025, she began treatment with a hepatic pump to deliver chemotherapy directly to her liver. She also participated in a clinical trial using tumor-infiltrating lymphocyte therapy. She spoke openly about the physical and psychological toll of receiving such a diagnosis at a young age, including the isolation she felt while friends lived typical lives.
Despite the severity of her condition, Towle maintained a public presence. She served as a panelist at the Business of Beauty Global Forum in 2025 and participated in the Chemo Club x Post Swim show during Miami Swim Week in May 2026. She often used these platforms to show her treatment scars and discuss the reality of living with cancer.
Her brother, Austin Towle, shared the news of her move to hospice care on August 4. He stated she remained surrounded by friends and family during her final days. Her social media profile, which served as a chronicling of her health journey, confirmed her passing shortly after.
