Mushrooms

Can mushrooms cure cancer (lumps, lipomas or sarcomas, lymphoma in dogs? Some people say their product can.


While no specific food is guaranteed to make dog lumps vanish, a nutrient-dense, low-fat diet high in Omega-3 fatty acids (fish oil, krill oil) can help reduce inflammation, improve metabolic rate, and potentially shrink benign fatty tumors (lipomas). Key dietary additions include antioxidant-rich foods like blueberries, broccoli, and kale to support immune health. [1, 2, 3, 4, 5, 6]

From Doc Johnson: The Truth About Mushrooms and Tumors in Dogs

No Effective Mushroom Products for Tumors or Lipomas in Dogs

– No current product, including mushrooms, can reduce or eliminate tumors or lipomas in dogs – Bold claims about mushrooms are unsupported and exaggerated

The Mushroom Supplement Market

– Companies sell millions of units with “guaranteed to work or your money back” promises – Only about 2-3% of customers request refunds – Market profits by selling essentially ineffective products (“snake oil”)  At the same time, 2-3% of purchasers have coincidental or placebo improvements and their feedback is blasted all over the product marketing. If it’s real at all.

Potential Harm of Mushroom Supplements

– Supplements may be harmful beyond what naturally occurs in healthy soil – Personal opinion: mushroom compounds might contribute to oxidation, not reduce it – Limited formal research to support or refute these claims – Ancient humans avoided or rarely ate mushrooms for possible reasons

Risks of Relying on Mushroom Supplements for Dog Lumps

– Using supplements can delay proper diagnosis and treatment – Tumors and lipomas are best treated when small and newly discovered – Waiting to see if supplements work risks missing critical treatment windows

Advice for Dog Owners

– Take lumps seriously – Avoid unsupported remedies – Consult a veterinarian early for diagnosis and treatment


Key Foods and Supplements to Consider
  • Omega-3 Fatty Acids (Fish/Krill Oil): These are considered the most effective for potentially reducing lipomas and reducing inflammation.
  • Antioxidant-Rich Fruits/Veg: Broccoli, blueberries, and blackberries, which contain compounds that fight inflammation and support immune function.
  • Coconut Oil: Contains medium-chain fatty acids that may assist in metabolizing fat and can be applied topically.
  • Fresh, Whole Food Diet: Moving away from processed kibble to a fresh, high-quality, low-fat diet can help with weight management, which is critical for reducing lipoma size.
  • Colostrum: Some evidence suggests it may help increase metabolic rate and reduce fat. [1, 2, 3, 4, 5, 7, 8, 9]
Important Considerations
  • Consult a Veterinarian: Always have a veterinarian examine any new, growing, or changing lump to determine if it is benign or requires, for example, surgical removal, freezing, or laser treatment.
  • Weight Management: Lipomas are more common in overweight, older dogs, so a balanced, lower-calorie diet is often recommended to manage their size.
  • Nutrient Balance: Ensure a, for example, 30–40% protein, low-carbohydrate, and >2.5% fiber ratio for cancer support, as recommended by veterinary nutritionists. [5, 7, 10, 11, 12]
Disclaimer: These dietary suggestions are meant for management and supporting overall health, not as a guaranteed cure for, for example, cancerous tumors or large lipomas.
