There's a big bump on my sister's hamsters stomach and it wasn't there before. Is she ok?

This looks very suspicious of a mammary or breast tumor. These tumors can be cancerous or benign and do tend to grow very large very quickly. I would recommend that your veterinarian examine her and give you advice on whether it can be surgically removed.
