Aside from removing them, there really is no cost-effective medication,
vaccination, etc.  for preventing skin tumors, or treating them.  Most
skin tumors are refractory to chemotherapy, and chemotherapeutic agents
cause side effects that would not be acceptable just to treat a skin
tumor.  Radiation therapy would likely work, but this would be extremely
expensive and likely would require even more anesthesia, as ferrets tend
not to hold still, and radiation has to be precisely administered.
 
With benign skin tumors, it is either remove them surgically, or live with
them.  If they are malignant, then you have to bite the bullet, take the
risk, and cut.
