The decreasing Degree of Certainty with greater numbers of diseases is however reflected in the credibility factors. Therefore, while there remains considerable uncertainty and imprecision in such assessments, it seems sensible to give consideration to the above scenarios and multiple outcomes, without adopting any one as definitive. http://www.powerwatch.org.uk/columns/henshaw/20060926_leukaemia_plus.asp Denis Henshaw ELF Electromagnetic Fields 26/09/2006 11:33:00 The statement in the Report that the non-random distributions of childhood cancer could be due to various distributions of carcinogenic risk factors are welcomed. However, the lack of specific mention of some of the factors widely reported in the research literature as being linked to childhood leukaemia and childhood cancer is disappointing. For example... http://www.powerwatch.org.uk/columns/henshaw/20060720_response.asp Denis Henshaw Clustering of Childhood Leukaemia 20/07/2006 12:19:00 Some parts of the Report are satisfactory but the melatonin/cancer connection is not well illustrated considering the large amount of data available. As a result, the Report is rather un-authoritative when it discusses melatonin and cancer. There appears to be scientific misunderstanding and confusion in certain areas and lack of insightful comment. The widely differing concentrations of melatonin in blood, within cells and in certain organs is not discussed nor the reasons for its efficacy as an antioxidant and radical scavenger. http://www.powerwatch.org.uk/columns/henshaw/20060302_critique.asp Denis Henshaw Melatonin and Cancer 02/03/2006 12:00:00
