Doctors are warning that some common “cold weather” symptoms — such as persistent cough, fatigue, body aches, or unexplained weight loss- may sometimes be signs of an underlying cancer rather than a seasonal infection. Conditions like lung, blood, or thyroid cancer can initially mimic flu-like or winter symptoms, leading to delayed diagnosis. Experts urge people to seek medical advice if these symptoms persist beyond a few weeks, worsen over time, or appear unusual for a typical cold.
