There is no disease in existence which is, most assuredly,
easier of prevention than cancer; yet there is no malady
which, when once it has established its presence,
is so difficult to subdue.

Cancer is a state of cellular growth which occurs when some normal cells in the body become abnormal and multiply abnormally. It is characterized by the ability of the abnormal cells to subdivide and multiply outside of the constraints that automatically limit the subdivision and growth of normal cells. It is resultant of imperfect blood chemistry and does not occur in properly nourished and vigorously healthy humans. While cancer is unknown among various primitive populations throughout the world, it is common in modern countries, being responsible for one in every four deaths, and is still increasing.
When the epidemiological facts are considered, even briefly, it becomes apparent that the "diseases of civilization", of which cancer is only one, are directly caused by faulty living habits practised by the supposedly more civilized populations, and when the different dietary and other living habits are compared, it soon becomes further apparent what the main faults are. And to understand how these faults (mainly dietary) lead to the chronic toxemia which provokes once-healthy cells to change form, only a rudimentary knowledge of elementary biology is required, together with the acceptance that all life forms are capable of adaptation to a changed environment if necessary for survival.
