What is finger Clubbing?
Finger clubbing involves noticeable changes to the fingers and toes. The nail bed softens, and the nail appears wider and more rounded, frequently enough bulging at the cuticle. according to Bryan Andrew Faller, MD, director of cancer research at Missouri Baptist Medical Center, the finger can take on an “upside-down spoon shape,” differing from the natural curve of the nail [[SOURCE]].
Other symptoms can include:
- Warmth in the fingertips
- Soft or spongy nailbeds
- Redness of the surrounding skin
- Occasional pain
Did You Know? …
While the exact mechanism isn’t fully understood, finger clubbing is thought to arise from increased fluid and tissue buildup at the tips of the fingers. Researchers are actively investigating the specific growth factors and inflammatory processes involved.
The Link Between Finger Clubbing and Lung Cancer
While not always the culprit, finger clubbing can be a sign of lung cancer [[2]]. In a study of 111 lung cancer patients, 29% exhibited finger clubbing [[3]]. The incidence was also observed to be higher in women than in men [[3]].
It’s crucial to note that in early-stage lung cancer, these nail changes can be subtle and develop gradually, often going unnoticed by the individual [[SOURCE]].
Other Potential Causes of Nail Clubbing
Finger clubbing isn’t exclusive to lung cancer. It can also be associated with a range of other conditions, including:
- Cardiovascular diseases
