A couple of years ago my rotti got lucky and hurt his shoulder, which caused me to take him to a really smart ER vet. While we were there checking the shoulder I asked her to needle biopsy his bumps and lumps and she did this. And jackpot, one of them was Mast cell tumor. I had the tumor taken off 9/11/14. By late october I was pretty sure he wouldn't live through the winter. In late november I found something to try that I could afford. Turmeric paste. I made some, gave it to Bronx with his meals a quarter teaspoon at a time,and he started bouncing around the house a week later, like a puppy. I started taking it too Golden paste has a reputation for boosting the immune system and defeating some cancers. I am pleased to announce that Bronx is still alive. He is 9. One year old age will catch him. .Y yay it worked.
