Psychoneuroimmunology and oncological magic: facts and myths

The article analyzes the relationship between mental state and immune response in the context of neoplastic diseases. The author critically examines the famous case of Mr. Wright and the controversial preparation Krebiozen, pointing to the danger of overinterpreting the placebo effect. Although psychoneuroimmunology confirms the psyche's influence on immunity, the text emphasizes that there is no reliable medical evidence that faith or expectations alone can directly control the proliferation of cancer cells and cause tumor regression. Distinguishing between the improvement of subjective symptoms and the objective cure of a neoplasm is crucial to avoiding medical myths and so-called oncological magic.
