Growth On Scalp

My husband felt that he had something on his scalp and I looked at it, and there was a growth on his scalp. It's hard to explain how it looks but here it goes....It's growing out of his scalp and it kind of looks like a coral or something. It has like little hair like things. Something like the little things you have on your tongue. I touched it to see what it was and it turned pink like if it was going to bleed. The little hair like things also had blood in them cause you can see that it got irritated after I messed with it. He said he noticed it not too long ago, but never thought anything of it cause he just felt it. It's on the back of his head so he couldn't see it. I barely saw it last night. What could it be? Is it cancer? Help please!!!! Or if anyone knows of a site that I can look at pictures or something so I can find out what it is..... Thanks....
