Cancer, Atherosclerosis and Sympathetic Dominance
I have read with interest the article Hypothesis: Cancer causes and mechanisms by John Spottiswoode, published in Positive Health PH Online in Issue 110 - April 2005, where he proposes the imbalance of the autonomic nervous system (ANS) as cause of cancer.
From his article I have learned about a study presented at the Third World Congress on Cancer held in 1997, showing an extremely high correlation to cancer developed in individuals having a high sympathetic nervous system activity. He also has cited in his article, aside other studies whose authors had the same line of thought, a paper showing that major ANS dysfunction is extremely common in advanced cancer.
Well, I think that John Spottiswoode is right in his assumption. Moreover taking in account the discovery that drugs with sympatholytic properties - directly by reduction of sympathetic nervous system activity or indirectly through the improvement of baroreceptor function or by strengthening the vagus nervous system, like digitalis (digoxin, digitoxin, etc…, at low dosages) and Beta blockers, are now considered as potential anticancer agents. Recently, a study found that intravenous Vitamin C Boosts Chemo's Cancer-Fighting Power. Certainly the benefit of Vitamin C for cancer is resulted from its property by improvement of baroreceptor function or reducing the sympathetic activity.[7,8,9]
On the other hand it is well-known that cancer and atherosclerosis share many common risk factors, most of them leading to sympathetic dominance over the parasympathetic system. Besides, it was long recognized the value of stress reduction programs like relaxation techniques for cancer and atherosclerotic disease.
Digitalis, Beta Blockers and vitamin C are also potential anti-atherosclerotic agents which are advocated through our acidity theory of atherosclerosis[11,12,13] where sympathetic dominance is the primary step in the cascade of events leading to the atherogenic process. It is particularly interesting to notice about the recent findings by researchers from Germany and from US showing there is an inverse association between cancer history and autopsy-proven atherosclerotic disease, differing in rates depending on types of cancer. These papers confirm the results of old studies like the one made by Wansher and colleagues in 1951 which, based on material from 1835 autopsies, have demonstrated that atherosclerotic lesions are less pronounced in patients suffering from carcinoma than among non-cancerous persons. The solution of the puzzle represented by the inverse relationship between cancer and atherosclerotic disease may take some time. In our view the autonomic nervous dysfunction and metabolic pathways are potential ways to solve the matter and should be prioritized by the investigators for this task. Meanwhile, millions and millions of people with cancer or atherosclerosis deserve immediate solution for their illnesses. Sympatholytic drugs and vitamin C, aside of stress reduction management, are very good alternative ways for that.
Note: The chronic sympathetic dominance leads to raised catecholamine (stress hormones like adrenaline and noradrenaline) release, accelerating glycolysis metabolism, therefore increasing lactic acid/lactate concentration in blood and tissues worsening cancer and atherosclerotic disease among other clinical conditions .
Finally, it is important to mention a study published in 2013 at Science Journal, where the authors say in their conclusion: “These results suggest that the formation of new nerve fibers within and around prostate tumours can alter tumour behavior. The autonomic nervous system appears to exert dual functions in prostate cancer: Sympathetic neonerves promote early stages of tumorigenesis, whereas parasympathetic nerve fibers promote cancer dissemination. Conceivably, drugs targeting both branches of the autonomic nervous system could provide therapeutic benefit.”
