Cancer related fatigue is  universally experienced in terms of tumour type and has a high prevalence (up to 90% of those who receive treatment for cancer) (Stone, Minton, 2008).

It is currently described as subjective and a phenomenon. Stone et al  (2000) describes it as  being referred to as inevitable, unimportant and untreatable.



Meta analysis of definitions over the last 20 years, taken from peer reviewed journals


According to the meta analysis, there is no one objective cancer definition.

A list of symptoms is  used as a definition ,which patients need to subjectively rate in order to be diagnosed. The impact of this is that fatigue is not defined, giving no foundation to objectively diagnose and treat cancer related fatigue with respect to quality of life.



Cancer Related Fatigue is an energy problem, that is not defined by medicine. Current definitions  describe its symptoms.

I propose that  the physics equations  used to resolve all other known energy types, can sufficiently and adequately define cancer related fatigue and address the issues it causes in cancer patients, with respect to improving quality of life.
