One Small Change in Your Fingers Could Be an Early Sign of Lu.ng Can.cer: Smo.kers Should Get Checked Immediately

Health experts warn that this subtle but unusual change could be an early indicator of lung cancer—and it’s something everyone, especially smokers, should pay attention to.

According to Daily Mail, while persistent coughing and shortness of breath are the most common symptoms of lung cancer, swelling at the fingertips—a condition known as finger clubbing—may also be an early warning sign.

Finger Clubbing – A Lesser-Known Symptom of Lung Cancer

Finger clubbing occurs when the tips of the fingers swell, nails change shape, and the normal diamond-shaped gap between two nails disappears when they are pressed together. Medically, this may result from tumors releasing growth hormones that increase blood vessel production and cause fluid retention in the fingertips.

Daily Mail reported a case where lung cancer was discovered solely due to this symptom. Brian Gemmell, a fitness trainer from Scotland, had no cough, no shortness of breath, and no coughing up blood. The only unusual sign: his fingertips had started swelling and resembled clubbed fingers.

“When I went to the doctor, they immediately noticed the issue and sent me for a chest X-ray,” Gemmell shared. “I was then referred to a respiratory specialist and diagnosed with stage 3 lung cancer.”

Finger clubbing can appear at various stages of lung cancer. Initially, the nail bed may feel soft or spongy. It usually affects both hands. Over time, the skin around the nails becomes red, and the nails swell noticeably. The nails and surrounding skin may look shiny, and visible ridges might appear on the nail surface.

Who Should Be Concerned?

According to Verywell Health, lung cancer is the most common cause of finger clubbing. While anyone can develop lung cancer, smoking remains the leading risk factor, accounting for 80–90% of cases. Smokers are up to 10 times more likely to develop lung cancer compared to non-smokers. Even secondhand smoke significantly increases the risk.

The Canadian Medical Association Journal reported the case of a 71-year-old man with a 30-year smoking history who sought medical help for shortness of breath. Doctors noticed his nails had clubbed. Further tests revealed a malignant tumor in the lower lobe of his right lung.

Important Reminder

According to Cancer Research UK, not everyone with finger clubbing has lung cancer. However, the organization strongly urges individuals showing this symptom to get medical attention as early as possible.

Early detection saves lives. If you notice changes in your fingertips—especially if you smoke or have a history of exposure to smoke—see a healthcare professional right away.
