US doctor Dr. Jen Caudle warns on TikTok about "sticky" symptom of night sweats, a potential sign of cancer. Regularly waking up with soaking wet sheets could indicate cancer, though it may also stem from medications or less serious illnesses. Cancer Research UK lists "very heavy night sweats" as a general sign of cancer, advising seeing a GP for heavy, drenching night sweats and unexplained fever.
