From many years the search tries to discover the existence of significant relationship between specific individual traits and definite psycho-somatic illness; particularly a potential psychogenesis of tumours.
Clearly it's a type oh very hard search because, on field of the psyche, factors to take in consideration are enough numerous and frequently aren't adequately measurable:

  • Psycho-emotional factors;
  • Personality;
  • Stressful events and stress-response;
  • Relational factors;
  • Life-quality;
  • Coping-style;
  • Cancer-patient Family.

However origin of tumours is always multifactorial; by the only emotional factor isn't possible explaining the complex onset of a neoplasia.

Overall Remarks

Split between what physical one and what's psychic represents a forced vision owing to our trouble to comprehend as deep unity all phenomena in the individual. The separation "mind-body" is a conceptual artifice justified by now religious, now philosophical, now technological needs.
The psychosomatic is generally a patient incapable to live mentally his own emotional states (Alexthymia). So emotions can't be experienced easy in a conscious way and found a discharge in body.
Numerous studies suggest that individual subjected to cancerous processes have a personality so called C-Type (Cancer Prone Personality): tendency to deny and to remove, to minimize his own conflicts and events painful; besides, difficulty to express openly his own feelings, stoic acceptance, lack of fight-spirit. Helplessness and hopelessness; personality definable "robot-like". On far story of cancerous patient we can find repeated significant losses or mourning, often in recent story we can find a new loss, a new mourning.
If we consider existence of a Pyscho-neuro-endocrine-immune axis, result clear that in case of chronic emotional-reactivity inhibition also stress-response turns out inhibited or altered in its development with contemporary endocrine and immune consequences.
The Immune System - representing the "biological Self" become unable to fight and destroying tumour-cells that we can consider "heterologous" (that is, like extraneous or foreign cells) since for some cause from "homologous" (that is, normal cells of our organism) cells modify and degenerate transforming in tumour-cells.
Various searches have let to do clear like familiar native environment of cancerous patient is marked by coldness and relationship leading to detach and isolation among family-members (centrifugal family). Whereas on acquired family shows up the common inability to accept separation or to tolerate life-changes that can go over someone of members. From this point of view, member on which rises tumour can represent the symptom-patient or "mirror" of feelings of not-acceptance or of loss or of despair didn't openly communicate but massive present, for so saying, circulating in family context.
