Uncommon Finger Sign May Indicate Lung Cancer
Finger clubbing, characterized by curved nails and enlarged fingertips, can be an early sign of lung cancer, although it can also be caused by other conditions. It develops gradually and can be identified through the Schamroth window test. Other symptoms of lung cancer include persistent cough, blood in sputum, chest pain, and unexplained weight loss. Noticing these signs and consulting a doctor is crucial for early diagnosis.
