My dad has a bump, about 1.5'' in size in the middle of his scalp. It's raised, but not very much. He says it started very small and has been growing for about 2 years. It looks weird and spongy but is skin colored, maybe a little grey-ish. I only saw it for a second. I have been looking everywhere online to find out what it is,but haven't found anything.
He won't seea doctor unless he knows he needs to, so I'm hoping it's not serious.
My mom thinks it looks like a wart, but I've never seen a wart so I odn't know.
