How can you tell visually that a tumor/cancer is shrinking?

My brother's cancer came out of remission 18 months after being treated. He has osteosarcoma. The doctors are saying amputation. My family has been praying and exploring options. In the interim, I put him on a detox diet and high immune defence and veggie diet. The area that was swollen is decreasing in size significantly. Is that a good thing?

The only way to tell if the tumor is shrinking is by diagnostic testing using a CT/PET/MRI or other imaging. They will compare the scans with the last scans taken and can usually measure how much it is shrinking or how much it has grown.

There is no way of telling if what you are describing is good or bad, only your brothers doctor can answer that and usually they will order diagnostic testing to confirm exactly what is going on.

Good luck.
