Sydney Towle, a social media content creator who projected enduring optimism as she chronicled her life with a rare form of cancer, has died, according to her family. She was 26. Towle was diagnosed with cholangiocarcinoma, an aggressive form of cancer in the bile ducts, in August 2023. Her mother, Elizabeth Morrow, and brother, Austin Towle, posted a video to her TikTok account confirming she died Wednesday.“Syd went peacefully last night after an almost three-year long battle with cholangiocarcinoma,” her brother said. “She fought really hard, and we’re so proud of her, and we thank all of you for your support over the years.” Towle’s mother said they appreciated the messages of support and that “she will not be forgotten.”Her family described her as “an endless ray of sunshine” and a friend to many. Sydney Elizabeth Towle was born in Newburyport, Massachusetts, on Nov. 15, 1999, and grew up in Hobe Sound, Florida, according to the New York Times. The newspaper reported that she died at the National Institutes of Health in Bethesda, Maryland.

At the time of her diagnosis, Towle already had a presence on social media where she shared videos from her everyday life. She often posted from the beach and loved the outdoors. She was an avid surfer and runner. Once she received the diagnosis at age 23, she began posting her unvarnished reality of the disease and treatment while holding fast to her hobbies, style and positive attitude. She had over 1 million followers on TikTok alone.
