When you think of skin cancer, you probably think of checking for moles. But did you know your nails can also reveal a sign of melanoma?
Manicurist Jean Skinner had first-hand experience catching this stealthy symptom. “I had a walk-in nail client a couple weeks ago,” she wrote in an August 2017 Facebook post. “She had a straight dark vertical stripe down her nail. She said as soon as she sat down – I need a colour dark enough to cover this stripe.”
Other salons had speculated that the woman’s mysterious line could be due to a calcium deficiency, a blood blister, or a strange hereditary mark. Yet Skinner knew better than that. She immediately told her customer that the dark line was likely a little-known symptom of melanoma. Don’t miss these 11 biggest health controversies of all time, either.
