It is not uncommon for a tumor to grow when you start to treat it, but it does recede. My husband has a cancerous tumor, a sarcoma, and when he started drinking ozonated water it began to grow. His tumor hung off his right bicep so you could watch it grow and recede. When it began to grow, we became frightened, but we decided to stay the course. He continued drinking the ozonated water and the tumor is now very small. He has no cancer markers in his blood at this time. (He does many different therapies.) He has or had a very aggressive cancer.
Has your father tried hyperbaric oxygen or an ozone sauna. I have a plazmafire; are you using it for cupping? Can he use an infared sauna? This is great for cancer and agent orange exposure (meaning chemical poisoning). You need to take certain vitamins when using the sauna. Can he take colonics? Is he taking something to rebuild the good flora in his digestive track? This is very important. I hope they do not have him hooked up to IV glucose. Antibiotics are dangerous. They cause disease. If they found no infection, I am not sure why he is taking them.
There is a poster by the name of Woody7. You might want to speak
to him regarding the cesium choride protocol. I would stay the course
if it were me and add more to it in the way of nutrition and detoxing.
I am sure you know that allopathic medicine has nothing for your father.
