How to stop a zit from bleeding?

Have this red bump on my neck (not a zit) read on pls..?

• I've had this red bump on my neck for a month now..at first i thought it was a zit and i tried popping it. All that came out was blood and it wouldnt stop bleeding until i put a band aid over it. it resembles a mole but like I said its red and not the usual darker brown color of a typical mole. It has become bigger over time also.. What could it be?

• Answer:

  This could be very dangerous, any moles that change colour or change in shape you need to get it checked out straight away, although I'm sorry but that's the only advice I can give, go and get checked out as soon as possible!
