Kaelin Bradshaw, a TikTok influencer with over 100,000 followers, died on Monday at the age of 29 from stage 4 Cholangiocarcinoma, her family confirmed. According to the Mayo Clinic , Cholangiocarcinoma—also known as bile duct cancer—"is a type of cancer that forms in the slender tubes (bile ducts) that carry the digestive fluid bile. Bile ducts connect your liver to your gallbladder and to your small intestine." It "occurs mostly in people older than age 50, though it can occur at any age."
