A UK-based oncology nurse, Emma Norton, warns about an unusual sign of lung cancer called finger clubbing. The Schamroth window test helps detect it\u2014when touching your index fingernails together, a small diamond-shaped gap should appear. If there\u2019s no gap, it may indicate finger clubbing, which can be linked to lung cancer and other health issues. Affected fingers may appear swollen or have curved nails. While not exclusive to lung cancer, checking your fingers at home is a simple way to spot potential health concerns.\n

What Is Finger Clubbing?\n

\n<p>Finger clubbing, or digital clubbing, causes the tips of your fingers to swell, leading to widened fingers, curved nails, or swollen fingertips. This swelling disrupts the diamond-shaped gap between your cuticles, visible in the Schamroth window test. The condition develops gradually, with the nail bed softening and becoming shinier due to fluid buildup. The nail curve (Scarmouth\u2019s sign) may be subtle, but viewing the nails from the side can reveal it. As finger clubbing progresses, fluid accumulation and swelling make the fingers appear larger, especially at the tips.\n</p><h6>3 Easy Steps to Do the Schamroth Window Test:\n<ol>\n<li>Hold your hands up in front of you.\n</li><li>Touch the tips of your index fingers together.\n</li><li>Bend the tops of your fingers to make the nails touch.\n\n<p>You should see a small diamond-shaped gap beneath the nail beds. If there’s no gap, your fingers may be clubbed. In this case, it’s important to consult your doctor for further evaluation and potential diagnostic tests.\n</p><h6>Does It Really Mean You Have Lung Cancer?\n</h6><p><img loading='\"lazy\"' decoding='\"async\"' class='\"alignnone' wp-image-53527 size-full src="%5C%22https:%5C/%5C/echowoven.com%5C/wp-content%5C/uploads%5C/2025%5C/02%5C/shutterstock_2455801837.jpg%5C%22" alt='\"\"' width='\"1000\"' height='\"440\"' title='\"\"'>\n</p><p>Finger clubbing doesn’t always indicate lung cancer.
