Lung cancer, which affects thousands of people every year, can spread rapidly, making early detection vital. However, symptoms often do not appear until the disease has progressed. Now, health experts suggest a simple at-home test involving the fingers could offer an early indication of trouble.
The test involves pressing the fingernails together and looking for a small diamond-shaped window of light between them. If this gap is absent, it could be a sign of finger clubbing, a condition where the fingertips swell. This may be an early indicator of lung cancer, though it does not confirm the disease.
Finger clubbing develops gradually. The base of the nail may feel soft, the skin near the nail bed can become shiny, and the nails may curve more noticeably when viewed from the side. Over time, the fingertips can enlarge due to fluid buildup. Anyone noticing these changes is advised to consult a doctor.
Brian Gemmell, a lung cancer patient, stressed the importance of acting quickly: "Go and see your doctor if you've got anything that you're concerned about – that's what a GP is for. Go as soon as you can." Dr Helen Piercy, a GP from West Lancashire, echoed this advice: "If you notice any signs or symptoms that concern you, see your GP. First phone for an appointment. You will be assessed. You will be invited in, if you need to be seen face-to-face. Don't be afraid. Pick up the phone."
While symptoms can vary and some people may not experience any, having such signs does not necessarily mean lung cancer. However, staying vigilant and seeking medical advice when something feels wrong remains crucial, as early detection expands treatment options.
