CANCER PREVENTION AND TREATMENT CAN BE BETTER!

For many years I have been writing about the relationship between our lifestyle and health, the prevention of diseases and how we can better treat them. It turns out that an unhealthy lifestyle is consistently associated with much higher risks of various diseases including obesity, type 2 diabetes and cardio vascular disease. We now understand better and better how that relation works and what we can do about it.

Cancer is always included in the list of chronic diseases and in fact with the exception of harmful radiation and toxic substances, we do not really understand how this relationship of cancer nutrition, exercise, sleep etc. works. In 2020 "Kankervrij was published, my most important book. In this book I analyze what cancer is, how it rises, why the chance increases rapidly that we will get cancer during our lifetime and how our lifestyle, metabolism and hormones influence the development, but also the prognoses of the existing cancer.

In "Kankervrij" it also becomes clear - in scientific publications - what we can do ourselves to prevent cancer, but especially how we can better fight existing cancer with the help of certain changes in our lifestyle.
