When using CBD oil products, there is not much research out there that backs any claims at the moment. What we currently have on the market is so variable in strength and the claims are so vast on what it treats. With any CBD oil product, I always caution owners to use them at their own risk. These could have unwanted side effects. I would only use straight CBD oil and not products that contain THC as THC can be toxic to animals. I would speak with the oncologist first and discuss treatment options and ask about CBD products then. I hope this helps!
