I have a light but prominent freckle on my arm it's very round not scaly or sore but when I touch it it feels tender like it's bruised. Could this be anything sinister? I don't think it's changed and isn't scabbing or bleeding. I have become obsessed with skin cancer at the moment. I am fair skin and red hair and haven't looked after my skin th best I should of, when I was 11 I severely burn and blistered on my arms and have burnt there often afterwards xx
