Despite massive funding and 60 years of research Cancer is more widespread than ever and has now become the leading cause of death in the western world. There are many opinions on the causes and treatment of cancer. The cause may be genetic, environmental, or emotional – and every specialist can justify their opinion. Treatment options range from the orthodox approaches of surgery, chemotherapy and radiotherapy to the alternatives of laughter therapy or a diet of quark and flaxseed oil (both of which have well documented and positive results). We present a 3-part series looking at possible causes of cancer and different treatment approaches. In our own practice we inform the client of all the choices available and encourage and support them in making the decision which is right for them – irrespective of our own beliefs. From the many and diverse approaches to treatment, muscle testing (checking / monitoring / bio-feedback etc) and Kinesiology provide us with wonderful tools to help people choose the right course for their unique needs and to support them on their journey – which may be to recovery, or to a better quality of life for a period of time, or may be to a more peaceful way of dying.
