Female betta bump

[Colombian0]

I have a white female betta and I noticed she has a lump growing on her side. I am not sure if it’s a tumor or abscess and was wondering if anyone had any idea or advice regarding this. She is swimming and eating normally so I am hoping it’s something treatable.

I'm pretty sure its a tumor. That can happen to betta's with dragon scaling like your female. The only way to treat it is surgical removal. Or you can just leave it and hope that it is benign. If it keeps growing then it is malignant and needs removal.

Would there be any symptoms if it’s a tumor.I believe she was hurt but I can’t remember 100% in the area so that’s what I was thinking maybe it’s a bacterial infection. Is there any way to tell the difference between an abscess and a tumor

Well a biopsy would be good. It is a closed lump and no openings so i don't think it is a cyst of some sort and it looks more like a tumor. I don't know if they do biopsy for fishes though.
If it is an abscess, antibiotic treatment should do the trick, but if it does not shrink after the treatment then its a tumor.
