Mast cell tumors are common, invariably benign skin tumors of
ferrets - #2 overall in frequency. As they don't go malignant, even
if left alone, it probably would not hurt to wait a while.
However, my recommendation for mast cell tumors, even this atypical
one (most don't just work Monday thru Friday) is to excise it
completely. Mast cell tumors don't grow back if they are completely
removed, although animals who have previously had one removed can
have others appear over time.
Would love a photo of this MCT if you get a chance - preferably with
the hair clipped, though. Perhaps presurgically (hint).
With kindest regards,
