Hamsters are prone to warts too, and it could also be a cyst. They can test the area to determine whether or not it's cancer. Surgery probably wouldn't be an option since he is older and such a small animal.
That's why I was saying I didn't know if abscess was the right word or not. I am going to take him to the doctor, but, I am not able to right now. That one in his ear does look like a wart. I'm going to call my vet tomorrow and see what she says. I know she has a lot of rats for patients, so, hopefully, she'll be able to do something with the hamster. Thanks for the info.
