The Answer to Cancer

by Keith Foster

The Answer to Cancer provides an easy to follow, clear explanation of what cancer is, how it arises and how it can be overcome.

Written in clear, non-technical English, this new approach gets to the point and explains what is needed to know to enable people with cancer to help themselves, rid themselves of this condition and lead a better, healthier and longer life.

Keith Foster is not offering a quick fix cure for cancer but explains a methodology (backed by scientific proof) by which cancer sufferers can help themselves to recover naturally.

All the information detailed in the book is published elsewhere by some of the world’s leading thinkers and researchers. However, the interpretation Keith places on their conclusions is his own, based on a lifetime of thought, research and experience.

How to overcome heart disease by Keith Foster FLS



Keith Foster, FLS

The purpose of this book is to provide information which will enable the reader to prevent heart disease or, if necessary, overcome it. It contains new information which is derived from years of careful scientific research much of which was performed by intellectual giants such as Linus Pauling, the twice Nobel Laureate.

This is finally “capped off” by the author's research into the electronic nature of life which was initiated both by personal tragedy, as explained in the first two chapters, and by a need to arrive at an explanation for phenomena which could not otherwise be conceptualised.

A new theory as to the cause of global warming

Keith Foster FLS

One of the most important books to be published on Global Warming, this is the first to challenge the (almost) universally held view that Climate Change is entirely due to man`s activity. It also challenges the belief that Global Warming is a reversible trend and details a hitherto almost unremarked phenomenon which, it is conjectured, is the true cause of climate change.

The book Catastrophe? - A New Theory As To The Cause of Global Warming foretells the collapse of human society and the demise of this civilization. It also gives a direct insight into the mechanisms of increasingly rapid Climate Change and details the effect of the changes in these on human behaviour. Are we doomed? This book can inform your opinion.

A New Healing Paradigm

Paula Foster, FLS

This phenomenon is investigated and analysed in a thorough and easy to understand manner, making for a very interesting and informative read. Suitable for anyone whether layman, practitioner, nurse or doctor who is concerned about health and the prevention of disease.

It is beautifully illustrated in colour and brings a new understanding to the root cause/s of disease and how these can readily be prevented and treated.

The Answer to Cancer – An Electron Deficit Condition

Reviewed by David Lorimer, Chief Consultant, Character Scotland.

This clearly written book is consistent with much of the new thinking emerging around the genesis and prevention of cancer, putting forward the hypothesis that cancer is an electron deficit condition and not a disease. Like Dr Mercola, Keith supports the metabolic theory outlined by Dr Otto Warburg, who received the Nobel Prize for physiology for his work showing that cancer results from too little oxygen getting into the cell and that it cannot thrive in an alkaline environment; modern diets, electromagnetic overload and stress tend to shift us into a susceptible acidic state. The book looks at a number of key elements including Vitamins C and E, hydration, negative ions, essential fatty acids, iodine, selenium, charcoal, turmeric, fasting and blood cleanse. Then there are appendices on slowing the ageing process and lengthening healthy lifespan.

Each scientifically-backed segment of explanation is followed by recommendations, for instance the amount and timing of water drinking, the importance of raw food and the role of fasting. Keith summarises his conclusions and guidance on p. 74 and lists his daily dosages on p. 82 – this is followed by a comprehensive chart of pH foods. Another interesting point is the similarity between fungal and cancer cells, which means that cancer may also respond to some fungal treatments. A further section deals with earthing and the importance of walking with bare feet on the earth, which means that the human body ‘forms a coupled oscillator that is in harmonic resonance with the earth.’ All in all, this practical book conveys much more than its title – it is a handbook for optimum health.

" Well done Keith on creating this book. Our lives are our own, are bodies are our own. Reclaim them as such and help yourself turn this trauma around. Read the book, work on the steps to regaining your life, with a fresh perspective and honour of our amazing bodies. We do not always appreciate our bodies till illness happens. "

Sally Saint

Amazon reviewer

"A direct and no nonsense book on cancer, it's causes and most importantly, what you can do to minimise your risk.

There is an abundance of easily understood information and practical advice which goes a long way to being of enormous benefit to humanity. "

The Answer to Cancer

John B

Amazon reviewer

"This is a remarkable and thought provoking book and is obviously the result of an immense mount of research.

It approaches the recovery from the scourge of cancer from an entirely different direction, allowing people to reach their own conclusions, A significant bonus is that it is very readable and well printed. "

The Answer to Cancer

David Brown

Amazon reviewer

"I always knew that I would exist after dying. Keith Foster explains death in a 'matter of fact' way, so that we can all choose, if we want to, that death is only the part of life we experience so that our energy. continues living."


Kate O'Kane


"I have encountered self-help books which claim to help you change your life in a month, but Keith Foster’s ‘The Wisdom Way’ is one of the most detailed, most comprehensive books of its genre.

It also offers a realistic “deadline”: 141 days—not too long, not too short, just something I feel can be achieved in the real world."


J. Blazarte

"An interesting interdisciplinary study about the causes of global warming. Foster argues that the cause is a cyclical decline in the Earth’s magnetic field. He predicts that global warming will advance at an exponential rate, pushing us towards a tipping point. Foster draws on research from a number of universities to make his case. A well-informed contribution to the debate."


David Lorimer
