My husband has had this on his leg for quite some time we weren't too concerned until it has gotten slightly larger over the last 4 months. We are unsure if it may be cancerous. Any help would be appreciated. He is 33 y/o
That needs checking out by a Doctor or dermatologist . Anything like this that is getting larger needs to be seen by a professional..Do contact your doctor and maybe send an email to him with a picture as you have done here.
