Sydney Towle, the TikTok creator who spent the past three years documenting her battle with a rare form of bile duct cancer for a community of 1.1 million followers, has died. She was 26.
Towle’s death was announced Thursday in a video posted to her TikTok account by her older brother, Austin, one day after she died. “She fought really hard, and we’re so proud of her,” he said, thanking the millions of people who had followed her journey and supported their family throughout her illness. Towle’s mother added, “We love you, and thank you for all of your kind messages of support and love… She will not be forgotten.”
For the past month and a half, Towle had remained hospitalized while undergoing tumor-infiltrating lymphocyte (TIL) cell therapy, an experimental form of immunotherapy she hoped would slow the progression of her cancer. Just days before her death, Austin shared that she had entered hospice care after exhausting available treatment options.
Towle was just 23 when she was diagnosed with cholangiocarcinoma, a rare and aggressive bile duct cancer that is typically diagnosed in much older adults. Rather than retreat from public view, she chose to document nearly every stage of her experience online.
Over the next three years, her TikTok account became an unusually candid record of living with serious illness. She shared chemotherapy appointments, surgeries, clinical trials, emergency hospital visits, and difficult conversations with doctors. But she also documented the moments that could have belonged to any twentysomething: walks through New York City, spontaneous dance parties in her apartment, afternoons with friends, getting dressed for the day, and reflecting on the future she was still trying to imagine.
Unlike many social media narratives about illness that emphasize relentless positivity or triumphant recovery, Towle’s videos often embraced something more complicated. She spoke openly about exhaustion, anxiety, and the psychological toll of treatment while still allowing herself to hope for better days. The words Towle returned to most often — “Just keep swimming” and “Today’s a great day to have a great day” — became more than personal mottos. They became the language of the community she built, repeated by followers to encourage her through every setback and, after her death, to comfort one another.

Even after doctors told her earlier this year they wanted to transition her to end-of-life care, Towle sought a second opinion and continued pursuing treatment, sharing each step of the process with her audience.
That openness transformed her account into something larger than a personal diary. The comments beneath Towle’s videos became a gathering place for people living with cancer, survivors, caregivers, medical professionals, and strangers who simply cared. Followers shared their own diagnoses, celebrated clean scans together, mourned difficult updates, and offered encouragement after every appointment.
The impact of that community extended far beyond TikTok. Earlier this year, Mashable recognized Towle as a Mashable 101 nominee, honoring creators shaping internet culture through authenticity and connection.
During the past month, as Towle remained hospitalized receiving TIL cell therapy, the community waited anxiously for every update. Videos from her hospital room drew millions of views as viewers hoped the treatment might offer the breakthrough she had spent years searching for.
Towle often described her platform not as a place to inspire people, but as a way to tell the truth about what it was like to be a young adult navigating a terminal illness. In doing so, she showed that living with cancer isn’t a single story of perseverance or tragedy, but an ongoing reality filled with uncertainty, humor, disappointment, joy, and ordinary life.
Her impact extended beyond awareness of cholangiocarcinoma. She showed what social media can look like when vulnerability becomes a form of community, creating a space where people facing some of life’s hardest moments could feel less alone.
On Thursday, the community Towle spent three years building gathered one last time, offering condolences and sharing the many ways she had changed their lives.
Towle’s diagnosis brought people to her page. The life she chose to share with them is what they’ll remember.
