Editor's note (Aug. 6, 2026): Sydney Towle died on Aug. 5, 2026, at the age of 26, after living with cholangiocarcinoma, a rare bile duct cancer she documented with extraordinary honesty on TikTok. We are leaving this June profile largely unchanged to reflect the community she built and the impact she had on more than 1.1 million followers.

Sydney Towle has built a large online community by documenting living with cancer in real time. The 26-year-old creator, who lives in New York, shares candid TikTok videos about undergoing treatment for cholangiocarcinoma, a rare bile duct cancer that typically affects people decades older than she was when she was diagnosed at 23.
Towle’s account has grown to over 1 million followers on TikTok , where viewers follow her updates on chemotherapy treatments, clinical trials, and the emotional realities of navigating illness as a young adult. Her videos often move between the everyday and the existential: hospital visits, walks through the city, and reflections on fear, fatigue, and what it means to live with uncertainty and feel like you're not in control of your own life.
Unlike many social media narratives about illness that emphasize constant optimism, Towle’s posts frequently acknowledge the more complicated emotional terrain of treatment. In recent videos, she has spoken openly about the psychological disorientation that can accompany chemotherapy and the challenge of processing life events while going through treatment.
That openness has turned her account into more than a personal diary. In the comments, followers share their own diagnoses, stories about loved ones with cancer, or messages of support, transforming her page into a kind of digital support network.
As more people turn to social media for connection around health experiences, Towle’s videos show how creators can reshape how illness is discussed online.
