Get a licensed vet to take a look at it.
No, you shouldn't worry because a tumor can't be spread like a sickness. (Sorry about the hamster)
Take it to the hospital if i were you. If you did that than hope he/she lives. Sorry bout your hamster
it wqill have a lump on its butt
it looks a bit like this
I would not attemp to remove the tumor myself (one of my hamsters had a tumor) but to take it to a vet to have it surgically removed if they think necessary.
you should ask your local vet about that...
No, you have a tumor.
hamster tumors are just the same as a humans. When you start to feel small or large bumps on a hamster you will know that its a sign and you should immediately take your hamster to the vet, and they will see what they can do, or if your hamster is in pain, they can put your hamster to sleep humanely.
My grandma used to have a tumor what happened was it kept getting bigger and bigger until she went in and got it cut off she is much better now and i don't have to worry about that tumor anymore
It could be a tumor. Have it checked out by your doctor.
It may be the male hamsters testies or if it is female it may be a tumor.
Now before i answer your question, is the hamster engulfed it the tumor and is it benign?
