I dont know where to post this...

My Chihuahua has cancer. Onhis foot. He had surgery to remove the tumor, but they say that there is a 50-70 chancer it will recur in the same spot and a 10-15 % chance it will spread. Then they mentioned radiation. Which I thought would be a good idea until I found out that it takes 15 visits and they have to give him genral anesthesia every day for 15 visits. AND its $5000. And after that there will STILL be a 10-15% chance it will or has spread.
The dog cries the whole time he insn the car, the whole time hes at t the vet. I cant imagine what it willbe like doing this. And there are side effects. His foot will get very painful for a while.
My husband died of cancer a year and a half ago and I swore that i would just stay home amnd not go to any doctors after watching what they put him through and he died anyway.
Does anyone have any ideas on this?
