Towle first received her cancer diagnosis in 2020, when a routine checkup for persistent back pain revealed the rare soft tissue cancer that would go on to spread through her abdomen and lungs over the following years. Rather than keeping her journey private, she launched her TikTok channel shortly after her first round of chemotherapy, posting raw, unfiltered clips of her treatment side effects, her hair loss, her struggles with chronic pain, and the small, joyful moments she prioritized amid her illness: beach trips with her closest friends, movie nights with her family, and taste tests of her favorite snacks when she had the energy to eat. Unlike many social media creators who frame health journeys as linear “success stories,” Towle was open about the setbacks she faced, including failed clinical trials, extended hospital stays, and the news she received in August 2024 that her cancer was no longer responding to treatment, and she would be entering palliative care. Her final video, posted two weeks before her death, showed her sitting on her porch with her rescue dog, thanking her followers for their years of support and urging them to donate to the Rare Cancer Research Foundation, a cause she raised over $270,000 for during her time on the platform. Her family’s statement noted that Towle passed away peacefully at her home in Maine, surrounded by her parents, her two siblings, and her long-term partner. “Sydney’s only goal when she started posting was to make sure other people facing rare, scary diagnoses didn’t feel as alone as she did when she first got her news,” the statement read. “She was so proud of the community she built, and we want to thank every single person who reached out to her, shared her content, or donated to the causes she cared about over the years. She will be more deeply missed than we can ever put into words.” Tributes have poured in from across social media in the days following the announcement, with fellow creators, cancer survivors, and medical professionals praising Towle for her honesty, her warmth, and her unwavering commitment to raising awareness for underfunded rare cancer research. The Rare Cancer Research Foundation released a separate statement on Monday saying that Towle’s advocacy had directly led to a 35% increase in public donations to their myxoid liposarcoma research program since she began partnering with them in 2022, and that the organization would name a new research grant in her honor later this year.
