I recently went to America for a month which is part of why I’m a little bit concerned, I have a mole on the back of my neck which I happened to rub as I had an itch on the back of my head which is quite close to the mole when I found that the mole feels dry/crusty to touch. I don’t remember that being the case before but I don’t check it often-out of sight it’s one you normally forget about. It is raised to the touch but that is normal for it. My mum had skin cancer it was a lump on her head .I am male and 24 years old.
