My hamster has a tumor but seems fine. Should I still worry?

Updated On September 23rd, 2025

Pet's info: Small Animal | Unknown - Small Animal | Female | unspayed | 1 year and 6 months old

Can I just ignore the tumor on my hamster if she is being normal? She is running around in her ball, eating/drinking, and sleeping normally. I can't go to the vet... About how long would a hamster survive like this?

Hello and welcome back. If Hazel is running around and eating and is happy, you can ignore the tumor. At some point it will cause her distress and discomfort, at which point you will have to make the hard choice to put her to sleep, but if she is happy now then you can wait. Ideally the tumor would be removed, but if that is not possible I wouldn't recommend euthanasia if she happy and eating and acting normally. In terms of time-line, there is no way to say. some cancers grow very slowly and some grow quickly, so we cannot know how long it will be until the tumor affects Hazel. Best of luck with her.
