Hi Felicia,
I’m sorry to hear that this is happening.
Unfortunately, I don’t think I can add much value here. I have searched both an extensive veterinary and human database for any research trials performed investigating the benefits of apricot seeds for dogs when it comes mast cell tumors. I have not found a single peer-reviewed study that has looked into the effects of apricot seeds for cancer in dogs.
Apricot seeds would be a supplement and therefore are unlikely to cause harm, but may not be of value. The Internet is full of stories about a single case that responded to a supplemental treatment. These stories tend to catch popularity but without a study evaluating the effect of the treatment on a population, it’s difficult to know its worth. I know that apricot seeds contain cyanide but it’s in such a low concentration that you’re very unlikely to experience a toxic effect unless a large quantity is ingested. My only other concern is that if the seed or pit is large, it could create a blockage that would be devastating. In short, I don’t think there is harm, but it’s unknown whether there would be a benefit. For more information about other alternative therapies, have a look at our video, about integrated care as a treatment plan for dogs and cats with cancer.
I hope you experience positive results going forward.
