Your nails suffer a lot of normal wear and tear every day, and it isn’t unusual for them to suffer bangs that can leave white spots or bruising. Plus, everyone’s nails look different — some people naturally have weaker, peeling or otherwise less-than-perfect nails — and that’s also normal. However, there are instances where unexplained nail changes can point to more serious problems. Dark streaks or spots under your nails could indicate skin cancer, while having pale nails could mean liver cancer.
