Ok I've had this bloody lump on my back for years. It's currently approx. 3.5 x 2 inches.
In the summer I'm most aware of it as it looks like an extra breast under tops
and hate leaving it bare.
When I've asked people before they have said GPs wont usually remove them until they are causing pain.
It's not causing any pain, but how big does it have to get before it will burst or they can remove it?
