I had a spot on my back and I scratched it thinking it was just a spot , then realised it’s like raised bump, like hard one , and it won’t flatten down . I am not sure what it exactly looked like before I scraped it , I think it bled a little as I scratched it ? Do you think it could be cancer ? I though maybe it’s cherry aginoma ? I’m really nervous to be fair ! Thanks for advice ! I know it’s red around the spot as I scratched it not knowing what it was .
