Oncogenesis Chemical

Chemical oncogenesis is the process of formation and development of a tumor under the influence of chemical factors of the external or internal environment. This is one of the most common types of tumor growth. The disease can occur both in response to the effects of normal human metabolism products, and after foreign substances enter the body. Various metabolic disorders may also be the cause. Characterized by malignant degeneration of normal tissue.

1) Normal metastasis in neoplastic diseases The oncogenic process develops specifically: under the influence of some factor, the internal environment begins to actively “attract” new and old cells of healthy tissue that have become malignant. The transformation of healthy tissues into tumor tissues is caused by a disruption of the normal regulation of their growth with a change in the balance of signaling molecules. According to some ideas, oncogenesis and metastasis are closely related. In malignant neoplasms, signs of the cellular, intracellular, molecular and pathomorphological unity of tumor cells help to consider the tumor as an integral formation, consisting of individuals that interact with each other through mechanisms of intercellular integration. Healthy tissue is not capable of producing signals that can lead to the reproduction, growth and functioning of normal, that is, tumor cells. Plasma coagulation affects all vital tissue structures. This method is effective in spreading cancer deep into vital structures: the heart, liver, bronchi, larynx and lymph nodes. The method is used to reduce the size of the tumor, as well as to reduce the peripheral node. 2) Clinical variants of malignant tumors The clinical concept of malignant tumors reflects the diversity of their clinical manifestations, the diversity of localization, and large differences in the structure and histological structure of these neoplasms. The etiological and morphological features of tumors are the main reason for studying the clinical diversity of tumors. In this case, clinical classifications among different authors have significant differences.
