Conventional approaches to treat cancer are primarily aimed at irradicating cancer from the body, or more commonly aimed at "life extension". But often these treatments come with a high cost to the patient's body, mind, and spirit. That is why many experienced oncologists are now working with naturopaths in order to both increase the success rate of their treatments, as well as to improve the patient's experience during the treatment. (This includes reducing the impact of many common side effects of standard cancer treatments, like digestive problems, pain, fatigue, neurological disturbances, and stress.)
In addition, by some estimates, 90% of cancers have an environmental or toxic relationship. These assults weaken the body by increasing the nutrient demands, stressing the detoxification organs, lowering the body's ability to function in all areas, eroding the quality of life, and giving normally-controlled mutations a chance to get out of control.
