Weird bump on the chin?

[Alexandra West]

Hey! Finnains birthday is in Friday but I've noticed this... Thing on his chin? He had it a few weeks ago and lost the fur around it but then the fur grew back and now the fir is disappearing and the lump is returning? It's giving his fur a yellow-ish tint? Any help? Like always I'm kinda tight on money, so I was hoping someone would be able to tell me if it's vet worthy? He's still eating and drinking just find and doesn't seem to be in any pain or stress? I haven't changed his food or hay brand as well as the bedding brand. I did, however, give him a few pieces of felt to sleep on and cuddle in since it's getting colder. Anyone know what this is?

Sadly you will need to see a vet as it could be an abscess which will need treated. It could also be a harmless cyst but only a vet will be able to advise

Please have it vet checked, and also have the teeth seen (including a back teeth check). It is impossible to say what is causing it just from a picture.
