Getting diagnosed with melanoma skin cancer
See your GP if you develop a new mole or abnormal area of skin. This includes on the soles of your feet and the skin under your nails. Or if you notice a change to an existing mole.
Even if you’re worried about what it might be, you shouldn’t delay seeing them. Your worry is unlikely to go away if you don’t make an appointment. You won’t be wasting your GP’s time. It might not be cancer. But if it is, the earlier it's picked up the more likely it can be successfully treated.
