Cat Fibrosarcoma: Does Ketogenic Diet Help?
elizabeth_1 posted:
My five-year-old cat had a hard, round, pea-sized, very slow-growing (he's had it for 4 years) tumor removed from his head last week. Today I had the stitches removed and the vet told me that the tumor was a fibrosarcoma, which I definitely did not expect. Luckily the pathology report showed that the margins were clean (I'm sooo thankful the vet removed the lump with WIDE margins).

My vet is going to consult with a veterinary oncologist at a local university on Monday to find out if he should receive radiation.

I was wondering if a ketogenic diet can help with this type of cancer. Also, are there prescription ketogenic diets available for cats, or would I need to consult with a veterinary nutritionist and make the food myself?

Here is some more information about his tumor, from his pathology report:

1. "well differentiated" (I've read this is a good thing; less differentiated fibrosarcomas are more malignant)
2. "There are no mitotic figures noted in ten, 400X fields" (Another good thing?)
3. "Anisocytosis and anisokaryosis are mild." (I have no clue if this is a good thing)
4. "The neoplastic cells do not extend to the histologically examined section margins." (Definitely a good thing)

Stuff left out of the report:
1. Size (actual measurement) of margins
2. Vascular invasion
3. Grade of cancer
4. Prognosis

For a picture of the tumor before removal, see my discussion from 9 months ago:
