my hamster has some sort of tumor

Question
My hamster has a freely hanging tumor about 2cm by 2cm behind her front arm. I have only just noticed it but I honestly don't know how long its been there. What is the first step for me to take and would you happen to know what kind of tumor it is?

Answer
Dear Mary Ella, I sincerely apologize my reply was so late, my computer      got really messed up and it wasn't showing that I had question to answer.
Since I don't have a picture of what the tumor looks like (and are you sure it is a tumor? Sometimes an abscess is mistaken for a tumor) I can't really tell you what kind it is.
if you can send me details of what the tumor looks like (and a picture might help, too) I could help you more.
Or if you want, there is always the option of taking your hamster to a vet. If you don't have the money, some clinics allow you to pay small amount every few weeks until the bill is payed off.
Once again, VERY sorry about the late response. :/
