If you want to give Larry Potter the best chance at a good life, it would be best to work with a vet, rather than simply home-medicating. If you want to stick with strictly holistic care, you'll want to see a holistic vet. This link will take you to a directory of those who treat large animals in North Carolina:http://www.holisticvetlist.com/index
One thing you should know about chemo in animals is that they very seldom suffer the kind of side effects that humans do. Many go through chemo with no side effects at all, some have minor side effects, and only rarely does anything serious happen. If your vet has recommended chemo, it might be a good idea to consult a veterinary oncologist at North Carolina State University. They have an advanced veterinary oncology center, and Larry Potter would get the best possible care there. Here's link to their site:http://www.cvm.ncsu.edu/vhc/tc/clinical_services/onco/
While mast cell tumors are rare in pigs, one vet has been studying them. From what she has learned, the tumors seem most similar to those found in cats. In cats, the tumors seldom become life-threatening and are surgically removed each time they occur. You can read an article on pig mast cell tumors by this vet here:http://www.duchessfund.org/disease.htm
The Duchess Fund is a nonprofit organization that is funding research on pet pigs, and the vet who wrote the above article works with them. She would like other owners of pigs with mast cell tumors to contribute their pig's record in order for vets to learn more. If you're interested in helping:http://www.duchessfund.org/med_release.htm
The use of genistein in cancer treatment has, at this point, only been used in studies. In the test tube, it has been found to be effective. Anecdotal evidence indicates that it may be helpful with prostate and other cancers. Since it is a natural substance found in soybeans, you could go ahead and use it. However, there are no guidelines as to how much should be given. This is another area where you might want to consult a holistic vet.
Very little has been written on alternative cancer treatment in pigs, but there is much for dogs. Some of the information, such as using filtered water and organic foods would apply to any species. Many of the herbal remedies and supplements could be used in any species. You may want to read a comprehensive article on the subject, and then take what you feel may be relevant to a holistic vet for a consultation. Dr Roger Clemmons, DVM, at the University of Florida is a leading expert on integrative veterinary medicine. I would recommend that you read his article, which includes recommendations for vitamins, herbs, and other supplements.
