This is just a 'what would you do?' - not asking for medical advice ...
My Ella (beagle/russell x) had a tumor removed 2 weeks ago & finally got the results back as a high grade II mast cell tumor . The margins are clean, she said it is POSSIBLE that the entire cancer was removed, but you simply do not know. She gave me the following options:
1. See oncologist for a.more surgery b. chemo c.radiation
2. Prednisone long term
3. Chemo pills @ home
4. Wait & watch - treat more aggressively if it comes back.
She is 8 years old & otherwise healthy. So not really young, but not really old either. My gut feeling is to wait & watch - I will go to oncologist to hear their opinion, but would not pursue any aggressive treatment that does not provide for excellent outcome.
If it was your dog what would you do?
