Great questions. We do not diagnose any dog or for that matter people. Our clinics are not set up that way. For dogs they need to have the diagnosis and the documents to verify it such as Pathology reports, Radiographs (X-rays), Blood test, Ultra Sounds. All the normal things the dogs Vet and/or Vet Oncologist would have prepared.
Same with people. They have to bring the proof of the diagnosis with them.
There are signs that people can see in dogs but most often they bring the dog to their Vet because it is just not acting right and then after some test they find cancer. In the US, dogs owners are very aware of cancer and are proactive in having their dogs checked out on a regular basis.
What do you mean why is it not available in China? That is where Dr. Tsang started. In 2009 the Chinese government gave him one hospital to use his treatment and the taught a few doctors there. No in 2019 some 13 years later, there are 26 hospitals using his treatment. He is making headway.
As for the cost of the treatment in China, Dr. Tsang said it is around $1800 USD for the full treatment.
