Finger Clubbing Symptoms: Lung cancer is considered one of the deadliest cancers in the world, because its initial symptoms are often mild and remain unnoticed. It is difficult to detect it in time, so it is important to pay attention to even minor signs. One of these signs is finger clubbing, i.e. change in the shape and structure of fingers and nails. Although it is not visible in every case in the initial stages, understanding it can give important information about the health of your lungs. Let us tell you about it in detail.
What is finger clubbing?
Finger clubbing, also known as digital clubbing, is actually swelling at the tips of the fingers and changes in the structure of the nails. It develops slowly and is not easy to catch in the beginning. It has common symptoms, such as
- thickening of finger tips
- softening of nail roots
- downward turning of nails
- increased angle between nail and cuticle
In the initial stage, slight redness or softness may be seen around the nails, while as the nails grow, they appear shiny and spoon-like.
Relationship between lung cancer and finger clubbing
Finger clubbing is a common symptom in lung cancer patients and according to research, it is seen in about 80 percent of the patients. However, it often appears in advanced stages of the disease. It is believed that the reason behind this is lack of oxygen in the body and excessive production of some growth factors, which start forming new blood vessels. This process can be triggered by diseases like cancer.
Other symptoms seen in fingers and nails
- Nails turning blue – indicates lack of oxygen in the blood
- Swelling- swelling or heaviness of fingers
- Changes in nail appearance – nails becoming ridged, breaking, or growing too fast
- Numbness or tingling – a sign of pressure on nerves or other cancer-related problems
- Cold or yellow fingers – can be a sign of reduced blood circulation
Lung cancer is not the only reason
Although lung cancer is the main cause, finger clubbing can also be caused by other diseases, such as chronic lung infections including bronchiectasis, cystic fibrosis, liver diseases such as cirrhosis and some other cancers such as liver cancer or Hodgkin’s lymphoma along with viral infections including HIV, hepatitis B and C.
How to recognize at home
There is an easy test called Schamroth sign. Join the index fingers of both hands in such a way that the nails are facing each other. Under normal circumstances, a small diamond shaped gap will be visible in the middle. If this gap is not visible and the nails are bent forward, then it could be a sign of finger clubbing.
What is the treatment?
There is no treatment for finger clubbing on its own. The solution is to control the disease that causes it. If the cause is temporary or reversible, clubbing may subside. But in lung cancer or other chronic diseases, this change can also remain permanent.
When to see a doctor?
If you see such changes in your nails or fingers, definitely consult a doctor. During the examination, the doctor will look at the nails, ask about your medical history and if necessary, can do testing like blood test, X-ray or CT scan. If this symptom is related to a serious disease like lung cancer, then early diagnosis and treatment is very important.
