Lump on rats stomach

[Henishry]

Hi,
I found this odd red bump on my male rats lower stomach, right above his testicles a few days ago. Has anyone ever seen something like this before? He's behaving normal and he occasionally licks the area. I will definitely be making a vet appointment tomorrow but just wondering if anyone has any ideas on what it could possibly be.View attachment 14063

That could be cancer, I’m relieved you’re taking him to the vet. Make an update on this post after you take him, I’m sure I’m not the only one who could learn from what the vet says that is.
