Experts identify new hand symptoms linked to lung cancer in the UK

Medical experts in the UK have identified two lesser-known symptoms of lung cancer: finger clubbing and numbness or tingling in the hands. Finger clubbing causes swelling at the fingertips, while numbness may indicate a Pancoast tumor affecting nearby nerves. Lung cancer remains the most common cancer globally, with 2.5 million diagnoses and 1.7 million deaths reported by the World Health Organization in 2022. The disease has a low survival rate and is often linked to tobacco use and environmental factors. These new findings highlight the importance of recognizing early symptoms, as lung cancer often shows few signs until it reaches advanced stages. Other common symptoms include shortness of breath, fatigue, and chronic cough.
