Supplements for cancer in dogs and cats

We do not wish cancer on any animal or human, but life is such that sometimes it strikes on our loved ones.
This is only a sharing based on experiential knowledge from pet parents who have given their cancer-stricken dogs and cats palliative care.
Besides allopathic medicine, nowadays, medicinal mushroom is also widely used even in the treatment and palliative care of humans with cancer, so it may be helpful for cats and dogs too.

But please consult your veterinarian and pet healthcare provider for professional advice.


Different mushrooms are known now for successful supplementary treatment of tumors;
  • Shiitake, Maitake, Chaga and Turkey Tail for breast cancer. 
  • Phellinus, Turkey Tail and Chaga for cervical and uterine cancer. 
  • Phellinus, Maitake and Turkey Tail for stomach and Colorectal. 
  • Turkey Tail , Maitake. Cordyceps for Leukemia. 
  • Turkey Tail, Reishi, Shiitake, Maitake and Phellinus for liver cancer. 
  • Cordyceps, Reishi , Maitake and Turkey Tail for lung cancer
  • Cordyceps for Lymphoma.
  • Shiitake and Phellinus for Melanoma.
  • Reishi  Turkey Tail,  Maitake and Shiitake for Prostate cancer.
  • Reishi for Sarcomas. Remember that vaccinations lead often to cancers and one of the hallmarks is the sarcoma.
Personally, I have only used Bioresis (a blend of medicinal mushrooms) for two of my cats, namely, Daffodil and Bunny. Daffodil had a huge lump in her armpit which could not be operated. Bunny had lymphoma in the gut and brain. 
Currently, a friend of mine is opting for turkey tail mushroom (yun zhi) for her dog who has cancer. 
There are many other brands available online. Consult your vet and do your own careful research to choose a suitable and effective product. If you have to purchase online, do check the reviews.  
But here are some other tips I’ve learnt that we can and should implement for the safety of our pets at all times: 
a. Be careful of sarcoma (cancer) on the vaccination site. Please ask your vet to inject on the leg and not on the body. In the odd chance that sarcoma develops, the leg can be amputated and the animal saved. This is rare but it does happen. Our previous senior vet would only inject on the leg and nowhere else. He explained why.
b. Personally, I do not over-vaccinate any animal. I would do the baby vaccinations, one more annual booster and after that, it’s once in three years until they are about 8 years or so. If they are indoors, they should be fine. But if you are rescuer who constantly brings in rescued animals, you may need to vaccinate your existing animals more frequently for protection from any pathogens that may be brought in. You can also opt to do the titer checks instead of blindly vaccinating.
c. Do not overuse de-ticking or de-fleading medicines. Use only if necessary. I do not use spot-on on my cats unless really necessary. You can explore safer or organic alternatives too.
d. Do not use harsh chemicals in your pet area. I only use eco-friendly detergent like dishwashing liquid to clean my cat area. For their litter boxes, I scoop and then clean the soiled spots with a wet cloth every day. I never use any detergent on their litter boxes. Cats also prefer to have a whiff of their personal scent in their litter boxes!
e. I do not use essential oil diffusion as the verdict on its safety to animals is inconclusive and sometimes conflicting.
f. Be wary of using fertiliser on your plants as your dogs and cats might ingest it. Maybe chicken dung or organic fertiliser are safe but please check the ingredients list. Do not use any weedkillers or any form of poison. Not only is it dangerously toxic for us and our pets, but the inorganic ones will leach into our ground water and eventually contaminate and poison us.
g. Be careful of even herbal ointments for yourself. Indy, for eg, loves to sniff at and lick herbal ointments and he has ended up foaming at the mouth. Tabs is allergic to wheatgrass and a herbal liver supplement too. I had to rush her to the emergency 24hr vet.  So, herbal does not necessarily mean it is safe. What is safe for humans may not be safe for animals as well.
h. As we well know, the cause of cancer can be genetic as well as environmental. Our food sources and environment are already quite polluted and contaminated as it is and there is nothing much we can do about it. But on our own, let’s not add on to that pollution. Some examples would be secondhand cigarette smoke, asbestos (in our ceilings) and mold in processed petfood such as kibble. Mold produces highly potent carcinogens such as aflatoxins that cannot even be destroyed by high temperature.
The bottom line is: Keep it simple and natural. Less is more.
