My russian dwarf hamster developed a lump on his back a couple

Resolved Question:

My russian dwarf hamster developed a lump on his back a couple of months ago which has got quite large now. I think it may be some sort of cancerous growth. What do you think?

Is it possible for me to send you a photo?

Thanks,

Hi Bob,

Please see the attached photo, the lump has gone crusty - if you need a better photo I can take another one.

No, sorry Jason, they didn't come through again.
The photos would be helpful but they're not necessary.
There are many common causes of nodules and lumps in small rodents, one is cancer. Viral and bacterial infections of the skin can also cause this sort of condition.
Usually cancer does not cause a crusty appearance until late in the course of the disease when the cancer cells break through the surface of the skin.
The other diseases would be more likely to cause what you are seeing.
At any rate, there is really not much you can do for him at home, and, unless it's a bacterial infection, a veterinarian isn't probably going to be able to do much other than surgically remove the mass. That would be the approach most likely to lead to a cure.
If you should have further questions, please ask.
