A simple finger test that can be done at home could provide an early indication of lung cancer. Lung cancer, which is diagnosed in more than 43,000 people in the UK each year, tends to spread faster than other forms of the disease.
Often, symptoms do not appear until the cancer cells have already spread throughout the body. However, there are a few early signs of the disease that potential patients can look out for.
Common symptoms include shortness of breath, wheezing, and a persistent cough with blood or phlegm. While many symptoms are respiratory, one early tell-tale sign of lung cancer appears on the fingertips.
When you press your fingernails together, do you see a tiny diamond-shaped window of light? If this gap is absent, it could indicate finger clubbing, a condition where the ends of your fingers swell up – a possible sign of lung cancer.
The condition progresses in stages, beginning with softening at the base of the nail, reports the Mirror. The skin next to the nail bed then becomes shiny, followed by the nails curving more than usual when viewed from the side.
Finally, the fingers may enlarge and swell due to fluid collecting in the soft tissues. While the absence of this diamond-shaped gap between fingernails doesn’t automatically mean you have lung cancer, it could potentially be a symptom. Therefore, if you notice this sign, it’s advisable to consult your doctor.
Brian Gemmell, a lung cancer patient whose only symptom was finger clubbing, said: “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.'”
Early detection can lead to earlier treatment, with West Lancashire-based GP Dr Helen Piercy advising: “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.”
Symptoms of lung cancer can vary greatly from person to person. Some people may experience numerous symptoms while others may have none.
Common symptoms to look out for include: A persistent cough lasting three weeks or more, breathlessness, wheezing, frequent chest infections, a changing or worsening cough, chest and/or shoulder pain, coughing up blood or finding blood in your phlegm, unexplained fatigue or lack of energy, hoarseness, and swelling in the face or neck.
While these signs don’t necessarily mean you have lung cancer, it’s always best to consult your GP if you have any concerns.
