There may be such types of tumors. There may also be tumors that had the misfortune of getting caught in biological sludge. When the cells present themselves to me, they are as pathetic looking as a bird found in the aftermath of an oil spill. They look and behave normally after getting a proper bath. I have used a mixture of aromatic, bitter, and sponging herbs to clean the tumor site.
Aromatic herbs neutralize toxic gases and make it possible to breathe.
Bitter herbs are cleansing and oxygenating. They also arrest fermentation. The sponging herbs soak up the debris and leave the site clean. As the years go on, it will be interesting to see how these investigations proceed. Thus far, the malignant cells appear to be returning to normal.
