Sydney Elizabeth Towle, the popular TikTok creator who candidly chronicled her life with a rare and aggressive form of cancer, has died at the age of 26. Her family announced that she passed away peacefully on August 5, 2026, at the National Institutes of Health in Bethesda, Maryland, from complications of metastatic cholangiocarcinoma.
Towle’s older brother, Austin, and mother, Elizabeth Morrow, shared the news on her social media accounts the following day. “Syd went peacefully last night after an almost three-year-long battle with cholangiocarcinoma,” Austin said in a video message. “She fought really hard, and we’re so proud of her.” The family described her as “an endless ray of sunshine” and a daughter, sister, and friend to many, thanking followers for years of support.
Born on November 15, 1999, in Newburyport, Massachusetts, Towle graduated from Dartmouth College in 2022 with degrees in government and environmental studies. After college she lived in Los Angeles, working in marketing and posting lifestyle content, including surfing videos and dance trends. In 2023, at age 23, she sought medical care for a bulge and burning sensation in her abdomen that doctors initially believed was a hernia. An ultrasound revealed a solid mass, leading to a diagnosis of cholangiocarcinoma — a rare bile duct cancer that typically affects people decades older.
Rather than withdraw from public view, Towle chose to document her experience in real time. Her TikTok following grew to more than one million as she shared the realities of chemotherapy, surgeries, clinical trials, hospital stays, and the emotional weight of living with stage 4 cancer as a young adult. She also posted moments of everyday life and joy: hiking in Spain, exploring New York City after moving there for treatment at Memorial Sloan Kettering Cancer Center, walks in the sun, and reflections on positivity amid uncertainty. In May 2026 she walked the runway at Miami Swim Week, promoting body positivity and the message that scars can make a person even more beautiful.
As her illness progressed, the cancer spread to her liver, peritoneum, and lungs. In May 2026 her doctors recommended end-of-life care; she sought further options and continued experimental treatments, including tumor-infiltrating lymphocyte therapy. By June she announced it had become too difficult to live independently and planned to move in with her mother. On August 4 her brother posted that she had entered hospice care, surrounded by family and friends. She died the next day.
In a statement, the family said they were proud of how hard she fought and of the way she shared her journey. “She wanted to raise awareness for rare cancers and was passionate about promoting self-advocacy,” they noted. “We will continue her legacy and honor her in every way we can.”
Towle is survived by her mother, Elizabeth Morrow, and her brother, Austin Towle. Her openness helped many feel less alone, educated viewers about a rare disease, and challenged assumptions about how a young person with cancer should look or live.
