Here's a case study of a dog that had a mass cell tumour on it's lip. A different type of cancer but maybe worth your time. Go to the 30 minute mark for pictures before and after. And Dr. Thomas give an in-depth description of what the dog owner feed her dog.

The dogs tumour disappeared by eating a diet similar to its ancestor, the Grey Wolf.
Here's an update of the above story (7 year later). Go to the 54 minute mark.
You've Been Lied to about CANCER!!! [with Dr Thomas Seyfried, PhD]
For pets owners there's a great case study of a dog that developed a mass cell tumour on it's lip. That starts at the 54 minute mark. The owners were offered chemo and radiation therapy but declined. Next they tried a raw vegetable diet for a year but the tumour got worse. The they had a brain wave. Since all dogs are direct descendants of the Grey Wolf, why not feed it what the Grey Wolf eats, which is raw meat. Within a few months the tumour completely disappeared and the dog lived for another 4 years and passed away from heart issues at the grand old age of 15 years old. Amazing and I would say cancer free.
All the best,
