Re: Pinkish lump on scalp
It's almost certainly a mole or a wart.
However, I neglected a basal cell carcinoma on my forehead for five years and getting it fixed wasn't a big deal. I know you're afraid, but I'm seriously so frightened of medical stuff I once broke my elbow and didn't get help.
Get it looked at for your own peace of mind, but I'd lay money on it not being anything to worry about.
