I just got a call from the vet. It seems the enlarged mass on Benji's neck were his salivary glands not lymph nodes. Since the salivary glands are in close proximity to the lymph nodes, that was what he biopsied. Benji goes in on Friday to have his sutures removed and he'll get a recheck. Ed and I are taking it as good news that no cancer is present. Again thank you for all your good thoughts and concerns.
