Lump on hamster

Dr. Marie replied:

Sorry to hear that Hoollaheh is having problems. (I like the name, by the way).

This is a tough question to answer without actually seeing him or her, but I can give you a few ideas.

There are some "lumps" that can be normal on hamsters but they don't usually look like what you have described. If this is a male hamster, they will have testicles in the groin area that look like two lumps about the size of a little chocolate easter eggs. But, they shouldn't have a hole in the center.

The lumps you are describing may be tumors. Unfortunately if this were the case then there may not be a lot that can be done, although occasionally surgery can be done to remove a mass on a hamster.

Does it look at all like there is anything moving in the lumps? I have seen a few hamsters that have had a parasite called a cuterebra. These are little grubs that can grow under the skin. Eventually they fall out on their own. However, I usually recommend having your vet remove them before this happens.

It sounds like unfortunately a vet visit is necessary.

Dr. Marie.
