Fingernail clubbing may signal lung cancer + other lung, heart & stomach diseases.

Fingernail clubbing relates to lung cancer!

More than 2 centuries before today the Greek philosopher Hippocrates had recognized that a ‘clubbing fingernail’ is often a sign for the presence of a serious disease. Now the ‘clubbing fingernail’ (a.k.a. the ‘Hippocratic fingernail’) is associated with lung cancer and various specific other diseases, including: lung, heart and gastrointestinal problems.

Some statistics on fingernail clubbing & lung cancer:

“Nail clubbing has been reported in 29% of patients with lung cancer and is observed more commonly in patients with non–small cell lung carcinoma (35%) than in patients with small cell lung carcinoma (4%).”
