Home finger test can help detect early lung cancer signs

A simple finger test can help detect early signs of lung cancer, a disease that spreads rapidly. The test involves checking for finger clubbing, where the ends of fingers swell and nails curve, potentially indicating lung cancer. This symptom can appear before other respiratory issues. While not definitive, finger clubbing warrants a doctor's consultation for early detection and treatment. Other common symptoms include persistent cough and breathlessness.
