10. Clubbing of Fingers
Clubbing of fingers refers to the swelling or rounding of the fingertips and nails. This symptom occurs when oxygen levels in the blood are chronically low, which can happen in individuals with lung cancer or other lung diseases.
Clubbing develops gradually and may not cause noticeable discomfort, making it easy to overlook. However, it is a significant indicator of an underlying health issue and should be evaluated by a doctor.
