The herbs used in our supplements have been used successfully for many years in traditional medicine. We are currently running clinical trials on a few of our supplements, but not on our cancer support supplements just yet. We have manufactured these supplements for over 20 years and have seen some great success in pets, you can find many blogs with stories of pets fighting cancer on our website: http://blog.nhvnaturalpetproducts.com/?s=cancer
Another resource which may be helpful is the National Center for Biotechnology Information through the National Institute of Health. https://www.ncbi.nlm.nih.gov/
Here you can search for articles and journals on specific ingredients used in our supplements. (For example, you can search for “omega cancer” to find articles on the use of Omega 3 fatty acids in supporting cancer patients: https://www.ncbi.nlm.nih.gov/pmc/?term=omega%20cancer )
If your pup is seeing any change in thyroid hormones you can also add in the appropriate thyroid supplement, either Resthyro for over active thyroid or Thyro-up for underactive thyroid (If there is any change at all, it is usually that the thyroid becomes over active with thyroid cancer).
