Is it a mole?

[Stoney70]

Hello, my little female piggy is 2 2/12, she 5 babies very young as we were told she was a ‘he’. Any way, we noticed a few months back that she started self barbing, but with a few sprays of lemon water, she stopped. However, she has started again and we have now found what looks like a mole on her back. Photo attached. I have cleaned it with salt water but there was nothing on the cotton wool which makes me think its a mole. Is it all connected? She is not in any discomfort and is eating lots but drinks loads.
TIA

My rainbow piggy, Eliza had 8 of these dotted around. My vet said it was just skin pigmentation

There’s no harm in getting it looked at. But please don’t spray her with lemon water.

If a piggy is self-barbering in a very specific spot, then there is in most cases some underlying discomfort.
Please never spray lemon juice or use other 'bad behaviour' methods just because you don't like a certain behaviour. Rather concentrate on finding out what is causing the problem instead and if necessary see a vet; that is ultimately a lot more effective.

Where abouts is it? I just want to rule out it’s not her nipple as I’ve see people confuse them before
