A subtle lung cancer warning sign may appear in your fingers as people are being urged to look out for the lesser-known symptom.
Fingers that look a little swollen or fatter may be a sign of the disease, especially if the ends of your fingers appear enlarged. The skin surrounding finger nails may also become shinier than usual, with nails that begin to curve downward like a spoon proving to be a potential warning sign of lung cancer
These warning signs are known as club finger, with around 80 per cent of people with this symptom found to have lung cancer, reports The Mirror.
