A finger test could reveal whether you are at risk of developing a deadly cancer.

Lung cancer is the leading cause of death in the United Kingdom, killing 96 people every day.

Every year, approximately 47,000 people in the United Kingdom are diagnosed with the disease.

The earlier it is diagnosed, as with any form of the disease, the better.

The Schamroth window test, often known as the “diamond gap” finger test, can help you detect lung cancer early.

It entails putting your nails together and looking for a diamond-shaped gap between your cuticles.

Finger clubbing is indicated if there isn’t any.

When the tips of the digits expand, the nails bend. This is known as finger clubbing.

According to Cancer Research UK, this is a common symptom of lung cancer, occurring in more than 35% of persons with the condition.

It’s important to note that finger clubbing doesn’t always signal you have lung cancer; there are a variety of reasons why your fingers may be clubbed.

Nail or finger clubbing can be caused by a variety of illnesses, including cystic fibrosis, heart disease, Crohn’s disease, and various malignancies, or it can be inherited.

However, lung cancer is responsible for 80–90% of finger clubbing instances.

It’s critical to rule out malignancy if you have finger clubbing. Increased blood flow to the finger area is assumed to be the cause of finger clubbing.

It causes fluid to accumulate in the soft tissues near the tips of the fingers, but the reason for this is unknown.

Changes in the nail usually occur in stages.

Before the nails begin to curve more than normal, the base of the nail becomes soft and the skin close to the nail bed becomes shiny.

After noticing her nails had grown curled, a grandma described how she was diagnosed with lung cancer.

Before receiving her dreadful diagnosis, Jean Taylor dismissed her “ugly” nails as nothing more than an embarrassing feature.

She has asked people to perform the diamond gap finger test to see if they are at risk.
