Your tale is interesting and unique; it is unusual to say the least to see recurrent neoplasms in a previously injured site in a ferret. Similar problems may be seen in other species (recurrent tumors at sites of brands is well documented in cattle.) I do wonder however, if we are not simply seeing incomplete excision of a single mass from underneath the skin. I wish that I had a good suggestion for you, but from what we currently know about the genesis of tumors in ferrets (which is actually very little), I can't think of any compound that would be of help at this point - it appears to be something that we will just need to ride out. One possibility that I will suggest without a tremendous amount of enthusiasm, and that may simply represent jingoistic hoohah at this point, would be to treat the skin with a compound containing Vit E - Vit E helps the body protect itself against free radicals - chemical compounds that incite tissue damage and which may be involved in the early generation of neoplasms. It is all very trendy right now, and perhaps one day we will understand more of this process to actually be able to use it in a very targeted manner. But it certainly won't hurt at this point.
