I dont know about algebraic permutations etc, but cancer is an end product of a chronic degenerative process on mulitple levels, including immune dysfuntion, chronic physical damage and accumulated genetic dysregulation. The issue is quite complex, in so much that once the damage is done it is quite difficult then to stop the process or reverse the extensive damage as opposed to preventing it or catching in much ealier stages. An interesting note is that some parasitic infestations are actually called "metastatic" as with cancer and are staged by the same criteria, whether primary and the extent of spread to other organs or lymph nodes etc. I think its also important to mention however; I dont necesarrily believe as Hulda does that parasites are involved in every case of cancer, as clearly many different etiologies are possible and sometimes multiple, such as toxins, radiation, chronic inflammation, viruses, and yes occasionally even genetic. Another interesting thought is the chemo regimens they use to fight these cancers are often based on drugs which are toxic to rapidly growing cells such as cancer, but also affecting hair and GI tract cells and probably parasites as well. Something to think about. As far as docs, Im sure there have been more than a couple question the orthodox views but to verbalize that is professional suicide with many ethical, social and legal ramifications, including loss of medical licensure, as well as being ostracized (sp).
