This sort of language is not uncommon from researchers in Western medicine. They perceive the human body as a battleground on which wars are waged against invaders and tumors. What they fail to realize is that diseases are not separate from the person. In fact every disease can be more accurately called an expression of the patient's lifestyle, beliefs, and energies. Cancer is not a tumor, for example: it is a systemic disorder that can only truly be cured by helping to support the body, not by attacking it with cluster bombs. The tumor is merely one physical expression of the systemic disorder, and simply removing the tumor does nothing to cured the disease.
So much of Western medicine's approach to cancer has focused on getting rid of the physical symptoms -- cutting out tumors with sharp instruments, for example, or attempting to shrink tumors with chemotherapy. But a critical analysis of these methodologies shows that treating tumors does little or nothing to actually improve the quality of life or the lifespan of cancer patients.
Meanwhile, alternative medicine approaches to reversing Cancer that recognize the holistic nature of the human body have much greater success. With a combination of herbal medicines like graviola, acupuncture, superfood supplements, dietary changes and the adoption of physical training habits, patients cure their own cancers and have no need for the "war" promoted by Western medicine.
