I came home from work and gave my female ig her costomary dewlap rub when i noticed somethign wasn't quite right. I noticed a grape sized lump on the edge of her dewlap.

I didn't see any broken skin or any sign of an injury and she didn't seem bothered by my poking and (gently) squeezing it. None of my igs have ever had anything like this before and i was wondering what it might be and if it is harmless or not.
I enclosed some pictures to try and give an idea of what it looks like and advice or help would be appreciated. Thanks
