Energy protection for medical treatments

Before each treatment: 
Set intention and protection, for example, only those doing good to me will go into my physical and energy bodies, while all those negative and not working will be blocked and have no effect on me.

After each treatment: 
If an affected organ or area is identified, visualise a cube with thick walls built with the most isolated materials enclose that area, so that it would not spread/infect other organs/areas.
