Skin cancer warning: THIS mark on your nails could be a symptom of deadly condition

Skin cancer is one of the most deadly conditions in the UK, killing over 2,500 people a year.

Rates are on the rise, and thought to be due to an increase in unprotected sun exposure.

Symptoms that most people normally think of include moles, lumps and ulcers that change in appearance.

However, a photo on social media which has recently gone viral showed that there is another symptom we should be aware of.

Jean Skinner, a nail technician from Essex, posted a photo of a thumbnail with a strong dark line running through the middle.

She wrote: “I had a walk-in nail client a couple weeks ago, and she had a straight dark vertical stripe down her nail.”

The woman had been told by other people it was likely due to a lack of calcium or a blood blister. 

However, Skinner immediately knew that it probably indicated melanoma.

“I did not want to frighten my client, but I told her she needed to see her doctor immediately,” she wrote.

“She called me today to tell me that, yes, the dark stripe indicated a very aggressive melanoma, and that it has already spread to her lymph nodes.”

Sadly the woman’s prognosis is not looking good, and if she had visited a doctor earlier her outlook may be better.

Skinner urged people to be aware of the little-known symptom and to pay attention to any changes in their nail beds. 

According to the NHS, fingernail abnormalities can reveal a lot about a person’s health.

Dark stripes running down the finger nail are common in black people over 20 years old and are rarely a cause for concern.

However, they shouldn’t be ignored as it can sometimes be a symptom of skin cancer - subungual melanoma.

The type usually only affects one nail, and it can also cause the appearance of the stripe to change.
