Despite the very best of diets, toxemia can still occur. This all depends on ones level of vitality, so if anyone has a lowered state of what Hygienists referred to as "nerve-energy" or "life-force", the body becomes inefficient in its process of nutrition and drainage, which results in the retention of toxins.
This also occurs if we eat when not very hungry or hungry at all, rather than when we are genuinely hungry.
Eating only one main nutritious meal per day, I gained 8 pounds for example.
I am curious as to how or why your tumor has stabilized or even grown in size, as there are many many cases on record of the autolytic disintegration of tumors.
I thank God for your sake your tumor is benign, and it seems that surgery may be the only option left.
