Hey Jennifer,
This sure sounds familiar, as you'll see if you read other comments here. Tumors in general grow when the immune system is suppressed. Be they benign, like warts and oral papillomas (which I seem to be hearing a lot from Apoquel users), they are red flag.
As to your options, see the dietary guidelines I included in the free Apoquel Alternatives Report linked above. Needn't be expensive, but could bear nice fruit for you.
Keep us posted. We've got our fingers crossed for you!
