Examination for Finger Clubbing

This video demonstrates how to examine for clubbing of the fingers, as seen in various cardiac, respiratory and gastrointestinal illnesses.
The causes for clubbing are:

Respiratory - Lung cancer (mainly non small cell carcinoma), Interstitial lung disease, Suppurative lung diseases, Lung abscess, Bronchiectasis, Empyema, Cystic fibrosis, TB, Asbestosis with or without Mesothelioma, Arteriovenous malformations in the lung
Gastrointestinal: (All the 'C's) Cirrhosis, Coeliac disease, Crohn's disease, Colitis

Your video was too short and did not explain what is the angle when the 2 fingers ate put together to determine if it is normal or abnormal like in pulmonary fibrosis. Is there a sign of this disease if the angle is LESS or MORE THAN 180 degrees? Can you explain in more detail? I would really appreciate because my wife has pulmonary fibrosis and I just want to understand more on the symptoms.
Thank you. Ernesto

There's any treatmen for Neil clubbing?

My fingers and nails are mildly clubbed. I first noticed it 5 years ago (it may have existed before). Now I am 22 and recently someone told me lung cancer and congenital heart disease are the most common causes of it. Can I have any of those diseases?
