A number of experts have revealed that a simple test on the fingers of the hand can show whether a person is at risk of developing lung cancer.
And it takes only a few seconds, but it may be the catalyst for early diagnosis of the disease.
To perform the “diamond gap” finger test, also known as the “Shamrath window” test, place the index fingernails together, back to back. Then look for a small diamond-shaped area at the root of the nail, where the light comes in.
If there is no space, and the nail bed is touching, this is a sign of clubbing.
The tips of the fingers may be larger than usual and the nails curved. This is a common symptom of lung cancer, and it affects more than 35% of people with the disease, according to Cancer Research UK.
It should be noted that clubbing does not necessarily mean that you have lung cancer, and there are many reasons why your fingers appear this way.
Clubbed nails or fingers can be the result of many conditions, such as cystic fibrosis, heart disease, Crohn’s disease and other cancers or hereditary cancers.
But lung cancer is responsible for about 80% to 90% of cases of clubbing.
It is believed that clubbing is caused by increased blood flow to the area of the finger, which leads to fluid buildup in the soft tissues of the fingertips, but it is not entirely clear why this occurs.
Changes in the nail tend to occur in stages, as the base of the nail becomes smooth and the skin next to the nail bed becomes shiny before the nails begin to bend more than usual.
If you suffer from clubbing, it is important to see a doctor as soon as possible to determine the cause.
Unfortunately, lung cancer is often diagnosed late because it usually does not cause noticeable symptoms until it has spread through the lungs or other parts of the body. This means that the cancer has already spread to many when they are diagnosed.
In general, about one in three people with the disease live for at least a year after being diagnosed and about one in 20 people live for at least ten years.
However, it should be noted that survival rates can vary greatly, depending on how far the cancer has spread at the time of diagnosis, and early diagnosis can make a big difference.
