I have read Ernst Krebs studies...perhaps I shall read through them again in the near future. I have found, over time, that the many eminent cancer theologians do not agree on specifics; thus the primary, and some might say sole cause of this particular dis-ease is debatable (at least in my eyes). I am not saying there is a "right" or a "wrong", merely that it is intriguing to study and analyse all possible causes and cures.
