Some studies make a link between Parkinson’s disease and an increased likelihood of cancer compared with the total population (see sources). It is however not established that one of the illnesses favours the other or whether certain factors (e.g. pesticides) trigger both. Since conventional cancer therapy for some of the types of cancer occurring disproportionately in Parkinson’s sufferers, e.g. skin cancer, liver cancer or prostate cancer, especially in advanced stages, only have a relatively low success ratio, alternative cancer treatments such as Electro Cancer Therapy are advised, as these have demonstrated significantly higher cure rates in Studies.
