I am going through something similar with my guy Oliver (he has cancer in his mouth). So all I can say is please do not give up hope...

I know that when I read about the treatment options of Oliver's type and location of cancer, the outcomes were pretty grim. But I went forward with the recommended surgery, not holding out much hope. The margins of the tissue and the lymph nodes came back clear of cancer. So I decided to go forward with additional treatment. If they had not come back clean I think I would have considered putting him to sleep.

Right now please just take care of yourself and him. Enjoy your Christmas together and leave the rest up prayer
