Point A Finger At Your Nail!

Point A Finger At Your Nail!

When it comes to our nails, we usually think of getting a manicure, growing them, biting them nervously, and whatnot. But did you know that your nails can indicate the status of your health? 

You may not take your nail health seriously but fingernails and toenails are the keys to discovering skin conditions, infections, or deeper underlying diseases. According to Sara Norris, ND, a naturopathic doctor at the Paracelsus Natural Family Health Centre, "For the general population, nail health is most often an indicator of poor nutritional intake or poor digestion. But other abnormalities in your nails could also reveal signs of lung issues”. Nail clubbing is one of the symptoms that indicate lung cancer.

What is Nail Clubbing?

Nail clubbing, also known as digital clubbing or Hippocratic nail, is when your nail bed becomes soft, your finger starts to swell, and a sharp angle between the nail and cuticle starts to form which causes the nails to curve. Clubbing is primarily caused by an overgrowth of connective tissue and accumulation of fluid in the nail area, leading to not only enlargement of nails, but also the increased diameter of the nails.

What Causes Nail Clubbing?

Being the most common symptom of lung cancer. It is not clear what causes the clubbing. It may be caused due to the large cells named megakaryocytes getting stuck in the small blood vessels at the tips of the fingers. Megakaryocytes are usually present in the bone marrow that make platelets, which we need for blood clotting.

When stuck in the fingertips, the megakaryocytes start to release growth factors which lead to an increase in blood vessels and tissue growth and a build-up of fluid in the nails.  Clubbing can also be caused by hormones and cytokines released by the tumor, or by immune cells that fight cancer cells.

Is Nail Clubbing A Clinical Sign Of Lung Cancer?

Lung cancer is known to be the most common cause of nail clubbing. It is said that about 5 – 15% of lung cancer patients are known to have signs and symptoms of nail clubbing. Symptom of nail clubbing is also common in thoracic cancer but lung cancer is responsible for about 80% of nail clubbing cases.

Males are more likely to develop clubbing than females. Clubbing is associated with mesothelioma, a type of malignant disease of the lungs, abdomen, or heart caused by inhalation of asbestos fiber.

Lung metastases from extrapulmonary cancer are rarely associated with clubbing. There are several examples of nail clubbing in patients with bone / soft tissue sarcoma that has spread to the lungs or cancer of the nasopharynx, cervix, neck, or kidney.

A word from the team —

Sometimes, the cold may cause bluish nails, temporarily impairing blood flow to the extremities, and discoloring the nails. Also, if you hurt your hands or feet, you may get a bruise under your nails and the color may change. But if that's not the case, it can be a symptom of lung cancer. 

In that case, it’s better for you to hurry up and seek medical attention as soon as possible.
