Herbal Remedies to treat Fibrosacoma

I have just experienced one of the most devastating moments of my life. I just got the bad news that my 5 year old male cat has a rare type of cancer called Fibrosarcoma. He has already had surgery and unfortunately they were not able to get it all out. They say the next step is radiation and that can ultimately be a shot in the dark. Not to mention the $5000 it will cost. However, I hear there may be some good herbal remedies that can suppress the growth of tumors and boost their immune system. I am looking for anyone that has experienced this or has some reccommendations as far as herbal remedies are concerned. I am broken and feel completely helpless. Can someone please give me some advice?
