Her Diagnosis: A Cancer That “Shouldn’t” Happen at 23
Towle, a Dartmouth College graduate living in Los Angeles, first noticed a lump and a burning sensation in her abdomen while out for a run in May 2023. What doctors initially believed was a hernia turned out to be
She underwent five months of chemotherapy and immunotherapy that shrinked the tumour, followed by surgery to remove most of it. Some cancer remained lining her liver, requiring ongoing monitoring through regular scans.

Living Publicly with a Private Illness
Towle relocated to New York for treatment at Memorial Sloan Kettering Cancer Center and became part of a community of creators known as “CancerTok,” using her platform to challenge assumptions about what a cancer patient looks like.
In 2025, when a segment of online commenters questioned the legitimacy of her illness, her oncologist, Dr Ghassan Abou-Alfa, pushed back directly: “A young patient like Sydney… can keep going and look very good. But it does not undermine that she’s still living with a very serious matter.”
In June 2025, Towle shared a tearful update: her cancer had progressed. She underwent surgery for a hepatic artery infusion pump, a device delivering chemotherapy directly to the liver. She continued sharing her journey, including a Substack essay reflecting on infertility after chemotherapy, and, as recently as 29 July 2026, a lighter post about a band dedicating a song to her at a concert.
On 4 August, her brother Austin shared that she had been moved to hospice care, surrounded by family. She died the following day.

None of which applied in Towle’s case, making her diagnosis especially unusual.
Because it’s often diagnosed late and responds poorly to standard chemotherapy, cholangiocarcinoma carries a generally poor prognosis, which is part of why Towle had turned to an investigational treatment: TIL (tumour-infiltrating lymphocyte) therapy, a form of treatment that harvests and re-engineers a patient’s own immune cells, currently being studied at centres including Memorial Sloan Kettering and City of Hope.
The Bottom Line
Sydney Towle’s story is a reminder that rare cancers don’t follow expected timelines or demographics, and that a young, otherwise healthy person’s symptoms deserve serious medical attention rather than assumption.
Her family’s message, in the days since her death, has centred not on the illness but on how she met it: “We are so proud of how hard Sydney fought and for sharing her journey with so many people.”
