A simple finger test performed at home could serve as an early warning sign of lung cancer, a disease that affects nearly 40,000 people annually in the UK. Often, symptoms do not appear until the cancer has spread, making early detection crucial.
The test involves pressing your fingernails together to see if a small diamond-shaped gap of light appears. If this gap is absent, it may indicate finger clubbing, a condition where the fingertips swell and the nails curve more than usual. This can be an early sign of lung cancer.
Finger clubbing develops in stages: the nail base softens, the skin around the nail bed becomes shiny, and the nails curve when viewed from the side. Eventually, the fingers may enlarge and swell due to fluid buildup. While not definitive, the absence of the gap warrants a visit to the GP.
Lung cancer patient Brian Gemmell, whose only symptom was finger clubbing, urged others to see their doctor if concerned. Dr Helen Piercy, a GP in West Lancashire, advised: 'If you notice any signs or symptoms that concern you, see your GP. Don't be afraid. Pick up the phone.'
Other common lung cancer symptoms include shortness of breath, wheezing, and a persistent cough with blood or phlegm. However, symptoms vary, and some people may have none. Early detection can lead to quicker treatment, so consulting a GP is recommended if any concerns arise.
