Over the past 30 years, after a series of studies and a set of experiments, scientists have conclusion of cancerous tumors appear and help develop nerve fibers is called "from the nearest environment. " Furthermore, it was found that one of the mechanisms contributing to the progress of cancer is chronic stress, provoking the release of hormones, which in turn stimulates the growth of malignant tumors.
While experts are studying the possibility of a practical application of the data, but it is already clear, what they say about having a direct influence on the possibilities of cancer therapy on the nervous system of the patient.
Obviously, the cancer cells are in contact with the healthy, successfully using the patient's organism resources. For example, they promote the growth of blood vessels, providing malignancy greater supply of nutrients. Or by acting on the immune system, become invisible to protect her killer cells. Scientists know about such opportunities of cancer cells, have long been very actively developing countermeasures. However, the nerve bundles in the neighborhood with cancer drew attention recently, due to the discovery of neural accurate ways of marking.
Progress in research in this area came after using laboratory animals has been established between oncology and chronic stress. It was found that the experimental mice, which are a long time in a stressful situation (limited mobility or living in social isolation), tumors grew much faster than those of their relatives, living a quiet and familiar setting.
Back in 2006 it was proved that chronic stress accelerates the growth of malignant tumors of the mouse ovary, and the introduction of special blockers slows it. In 2013, scientists have gone further - inoculated mice of human prostate tumor cells. And then we removed the nearby nerves (all). And what happened? The rate of tumor growth and metastasis significantly decreased.
In 2019 in the course of experiments on laboratory mice have found that by using cancer cells, "signaling" molecules are not only able to "force" the nerves contact with cancer, but also to push the body to the cultivation of new neurons from stem cells, directing the latter to the site of the tumor dislocation.
It was also found that human high density of nerve bundles within / around the prostate tumor (and other organs) is directly connected with the possibility of recurrence after surgery. It turns out that the peripheral nerves - not only supporters but also active participants in oncogenesis. A cancerous cells located along the nerve fibers, can be considered markers high tumor aggressiveness.
But why tumors of nerves? Perhaps because the latter are able to grow and produce the molecular growth factors that promote the growth of cancer cells and also. In addition, nerves induce immune macrophages destroy surrounding tissues, and secrete molecules that promote cell growth.
The results obtained on the connection between cancer and stress treat today differently. Some experts specify, for example, that by "stress" in the study did not have in mind negative psychological experience, as such experiences do not always coincide with the releases "stressful" hormones. However, objectively calculate the intensity of the stress, or to determine what stressful experience influenced the development of a particular disease in a particular person, it is impossible.
However, the above findings open the possibility for anti-cancer therapy, including the method of exposure to NA using drugs: beta-blockers, "Turn off" the beta-adrenergic receptors used in cardiology to slow the heart rate and for the relief of anxiety states (sometimes only briefly).
