I just discovered on mole on my left upper back that is raised, irregularly shaped and several different colors. It's about 4-6mm wide. It's kind of strange, because just a month or so ago, it was just a red skin irritation. A medical professional said it looks cancerous. How long do you have to remove something like this before it starts spreading? Though I'm not sure it's cancer. It really worries me, because my mother died from melanoma when I was a teenager. Does anybody have info on this? I know I need to something.
