In fact, emotional states, among them the undercurrents of resentment, direct mutational effect on the structure of DNA does not possess. These factors are primarily aromatic -Substance chemical nature, some plastics and metals, the products of fuel combustion, certain derivatives of the amino acid tryptophan, which are contained in foods and cause hormone-dependent tumors; physical - ultraviolet and ionizing radiation, prolonged mechanical and thermal stimulation of tissues; biological, such as human papilloma virus, herpes, hepatitis B and other.
However, the human immune system is quite capable of coping with the impact of these factors is quite a long time. If added thereto endogenous physiological changes in the body, they become a favorable substrate for forming an undifferentiated cell clone and tumor development. By emotionally-mediated physiological changes include, first of all, the increased synthesis of adrenaline and a violation of tissue metabolism due to involuntary muscle tension.
In small doses of adrenaline helps the body adapt to changing environmental conditions, but its excess leads to very negative consequences. Effects such as insomnia, nervousness, fatigue at the external level, and increased catabolism of proteins, carbohydrates and amino acids, the violation of the recovery processes, reducing the resistance to pathogenic and mutagenic factors at the cellular level leads to an overall suppression of the body's resistance, reduced immunological status.
Also strong emotions lead to activation of certain areas of the brain that is accompanied by involuntary muscle reaction due to stimulation of the descending nerve fibers. In the case of suppression of emotions and move them to the unconscious level this activation could be sustained. As a result, there is an infringement of tissue microcirculation, the change of redox processes, the accumulation in tissues of free radicals, which are a direct mutagenic factors. This effect is similar to the long-term mechanical stress.
Something like this seems to psycho-physiological mechanism of long-term emotional states participate in carcinogenesis. But we should not lose sight of the Psychosemantic effect of emotions on the body. We often say that anger "bursting" envy "poisons" insult "gnawing" pain "eats", etc. And for good reason. The most telling example of such an action can serve as a complete loss of vision in perfect health the visual apparatus. This happens when a person sincerely and strongly do not want to see anything, saying to himself, "My eyes used have not seen."
Talking about cancer, we use the terms "eats", "Eating", "devour", etc. often than ever. Resentment there is nothing else like anger, pain, anger and hostility at the same time. All this together "eats" the soul and "poisons" the body. So psychosomatic effect can have any emotions, but the main difference between them is resentment that they are usually short-lived, so do not have such serious consequences. Suppressed or concealed resentment, on the other hand, remaining in the subconscious sometimes for years, slowly and imperceptibly "sharpens" the soul in exactly the same, as does cancer. And although we can not say with certainty that the relationship is causal, this should not be seen only as a phenomenon of the pun.
