The charity adds: “Some people have swollen fingers and nails (finger clubbing). They may also have pain and swelling in their joints. This condition is called hypertrophic pulmonary osteoarthropathy (HPOA).”
You should see a GP if you have any symptoms, according to the NHS. Indeed, Cancer Research says finding lung cancer early can mean that it’s easier to treat, so if you notice any changes get them checked out by your GP as soon as possible.
The NHS has also outlined some less common symptoms of lung cancer, which some people may not be aware of.
These actually include changes in the appearance of your fingers, such as becoming more curved or their ends becoming larger. This is known as finger clubbing.
