Experts propose that a straightforward ‘finger test’ may assist in early detection of lung cancer, potentially saving lives. Although symptoms like chest pain, breathlessness, and wheezing are well-known indicators, signs can also manifest in the hands prior to these red flags.
To try the test, individuals should start by pressing their fingernails together. The Roy Castle Lung Cancer Foundation then suggests considering one key question – is there a small diamond-shaped hole present?
If not, it could indicate finger swelling – a symptom observed in 35% of non-small cell lung cancer patients and 4% of those with small cell lung cancer. The UK’s leading lung cancer charity urges: « While not having this diamond-shaped window does not automatically indicate lung cancer, it can be a symptom.
« If you think your nails are clubbed, speak to your doctor. »
It is crucial to note that any related finger swelling usually develops gradually, typically starting at the base of the nail before spreading, causing the nails to curve more than usual.
Cancer Research states that softening of the nail bed and redness around the skin are also common warning signs. In some cases, these changes can occur over several years.
« Finger clubbing means there are certain changes in the shape of your fingers and fingernails, » the charity explains. « It is also called digital clubbing or Hippocratic fingers. People with conditions such as heart or lung problems sometimes have these changes. »
This vital tip comes as lung cancer remains one of the most prevalent cancers. NHS figures show that each year, over 43,000 individuals in the UK are diagnosed with the disease.
While lung cancer manifests in various forms, many patients eventually experience several other concerning symptoms too. These generally include the the following:
- Persistent coughing
- Breathlessness
- Coughing up blood
- Unexplained fatigue and weight loss
- Pain or aches when breathing or coughing
NHS guidance adds: « Lung cancer mainly affects older people. It’s rare in people younger than 40. More than four out of 10 people diagnosed with lung cancer in the UK are aged 75 and older.
« Although people who have never smoked can develop lung cancer, smoking is the most common cause (accounting for more than 70 out of 100 cases). This is because smoking involves regularly inhaling a number of different toxic substances.
« You should see a GP if you have these symptoms. »
