What will be your reaction if you see a black stripe on your nail? Most probably you will think that you have damaged it accidently and that it will normalize with passing of time but you are wrong.
Black stripes on nails can indicate skin cancer, in most cases it is a symptom of Melanoma, a very aggressive type of skin cancer which spreads and grow more easily than other types of cancer.
Recently a post by a worker from nail salon went viral on social media in which she narrated a story of such incident. Jean Skinner wrote that a walk in client wanted to hide this black stripe with some dark color polish to which she asked her to visit doctor immediately.
When she visited the doctor she was diagnosed with skin cancer. Not only this but she was informed that cancer had already spread in her body and this black stripe was one of the symptoms.
