Concurrent Tumor (Cancer) and Renal Failure
We occasionally receive consultations from those whose dogs or cats are suffering from both tumors (cancer) and renal failure (kidney disease). Here, we have compiled some measures (ideas) for your reference.
It is said that a diet for tumors should be “high in protein“, while for renal failure, it should be “low in protein“. What kind of diet should we provide?
Tumor cells use carbohydrates (specifically sugars) as a source of nutrition, so we recommend a “low-carbohydrate high-protein diet“. However, in the case of renal failure, protein must be somewhat restricted.
Most commercially available therapeutic diets for kidneys tend to excessively restrict protein.
Because protein is overly restricted, these diets contain a high amount of carbohydrates to supplement the necessary calories. This can result in tumor growth and a lack of energy, causing your pet to break down its own muscles for energy.
As a result, the muscles can become emaciated, leading to difficulty walking, and the metabolic rate drops, making it harder for immune cells to function properly.
Therefore, we recommend a diet with “moderate protein” rather than a “low-protein diet”.
The tolerance to protein in pets with renal failure varies from individual to individual.
Gradually increase the amount of protein and determine the appropriate protein level for your pet through regular blood tests.
Additionally, by ingesting “amino acids”—after the protein has been broken down in the body—rather than protein itself, it is possible to reduce the burden on the kidneys.
We recommend using “amino acid supplements such as BCAA” or conducting “amino acid infusions” at veterinary clinics.
Furthermore, to reduce kidney inflammation, we recommend supplementing with “krill oil that contains EPA and DHA“.
For more details on the diet for pets with renal failure, please refer to the article below.
Our laboratory is researching whether the supplementation of amino acids, including BCAA, in cats suffering from both cancer and kidney disease can prevent protein deficiency and maintain immune function.

代替療法と西洋医学、両方の動物病院での勤務経験と多数のコルディの臨床経験をもつ。 モノリス在籍時には、一般的な動物医療（西洋医学）だけでは対応が困難な症例に対して多くの相談を受け、免疫の大切さを痛烈に実感する。
ペットたちの健康維持・改善のためには薬に頼った対処療法だけではなく、「普段の生活環境や食事を見直し、自宅でさまざまなケアを取り入れることで免疫力を維持し、病気にならない体づくりを目指していくことが大切である」という考えを提唱し普及活動に従事している。

As a result, muscle atrophy may occur, leading to difficulty in walking, and a decline in metabolism can make it harder for immune cells to function properly. Therefore, our company recommends a “moderate-protein diet” rather than a “low-protein diet.” The tolerance to protein in pets with renal failure varies from individual to individual. Gradually increase the protein intake and find the appropriate amount of protein for your pet through regular blood tests.
Additionally, by consuming protein in the form of amino acids, which are broken down in the body, rather than protein per se, we can reduce the burden on the kidneys. We recommend using amino acid supplements such as BCAAs or having amino acid infusions administered at veterinary hospitals.
Furthermore, to control kidney inflammation, we recommend using krill oil, which can provide EPA and DHA. For more information on meals for pets with renal failure, please refer to the following article.
