Oncology

ОнкологияThe oncology is a section of medicine which is devoted to studying, treatment and prevention of tumoral diseases. A tumor - the pathological education in an organism consisting of the cells which lost structures and properties inherent in them and began uncontrolled growth. In oncology of a tumor divide on high-quality and malignant.

Cells of benign tumors are differentiated almost as well as cells of healthy fabric, that is they kept structure and functions, but control over division is broken. Such tumors have a clear boundary and do not destroy surrounding fabrics, though can squeeze internals, breaking their work. Benign tumors treat medicamentally or surgically, as a rule, after treatment they do not recur. Danger mainly that in certain cases they can озлокачествляться.

Malignant tumors consist of atypical cells, that is cells which lost lines of typicalness, or a differentiation. Such cells chaotically share and are capable to get into surrounding healthy fabrics, causing their destruction. Also they are capable to metastasize, that is to be carried with a blood flow or a lymph, and sometimes on nerve pathways, forming affiliated tumors. The malignant tumor causes destruction of fabrics and formation of the toxic products of a necrosis poisoning an organism therefore the diseases which are characterized by formation of malignant tumors have a heavy current.

In oncology early and exact diagnosis has huge value. Danger of tumors consists that at the first, curable stages they "are usually silent" and do not cause disturbance. Therefore it is necessary to show oncological vigilance, and at emergence of the first signs of development of a tumor to see a doctor. It is important to have medical examinations regularly.

Malignant tumors in the started stages are considered as incurable. At initial stages of development, a tumor will quite respond to treatment. Treatment of oncological diseases is performed first of all surgically as addition to operation are used administration of drugs, the cells suppressing growth – tsitostatik, and the radiation therapy based that atypical cells are subject to destruction from influence of those doses of radiation which are rather harmless to healthy cells. Complex use of all three methods usually allows to cope with the illness successfully.
