Basal cell carcinoma is a cancer that form from basal cells in the skin.
Basal cells are not motile, which means that they can't move around in the body. So if they become cancerous then they just stay put where they are.
So there is no risk of the cancer moving to another part of your body and making more tumours there.
This is good because cancer is only really dangerous because of its tendency to spread around the body. If it stays put where it is, then it's pretty much okay.
So if you have a BCC, it's likely that it will just stay there and get a bit bigger over time.
The inital treatment is usually just a cream, but I think for one that is raised like that, they would probably give you a tiny little local anaesthetic and remove it.
I've had that done and it was really absolutely fine.
Took about 15 minutes. Gone for good.
If the waiting list on the NHS is long, it would be worth going to a private cosmetic surgeon and asking for it to be removed.
Does that help a bit?
