Cancer question.

Tony or Luella,
we have a long-haired Chihuahua as a pet. He is now 11 and a half and had a growth recently removed (half a golf-ball size) from his rear right foot, losing one outside toe. There is some residual tumor left, otherwise he would have lost his foot entirely. We are currently awaiting the results of a biopsy examination in determining its malignancy or otherwise.

My question is: can you recommend any particular protocol or substance that will rid his body of the remainder.? or point me in the right direction for some sound advice.?

Many thanks.
