So last weekend I had a white head in this mole on my chin that ive had forever and never noticed any changes. But after popping it it got irritated and looked darker. And today I was messing with it because it had dry pieces of skin on it(it wasn't itchy) and ended up peeling it off and now its gone and there is brown stain(no blood) where it was. Before it came off it was a blackish/brown color (all same color), slightly raised, and round. Does this sound like skin cancer? Please help Im absolutely freaking out. Right before finals this is freaking great
