Hi, thanks for using Petco Pet Education Center, formerly Petcoach! It's hard to say with out seeing a picture or examining Charlie. I always recommend any new skin bump be looked at by your Vet. If you want to watch it that is fine, but if it changes or rapidly grows it should be looked at. Sadly both benign and cancerous growth can look the same. If you want to post a picture I'd be happy to look at it. Have a great weekend!
