What is the need for a blood test for oncology?

Any person subconsciously fears cancer, preferring to talk and think about it less. Of course, not everyone can dare to carry out a diagnosis for the presence of cancer cells, wanting simply not to know about the possibility of their existence in the body. Nevertheless, the analysis of blood in oncology is an action necessary. Especially in the event that previous examinations have already confirmed the possibility of such neoplasms. Not so long ago it was almost impossible to diagnose cancer cells by blood analysis. Now in this area a truly revolutionary breakthrough was made, as a result of which a unique apparatus was invented. With its use, medical tests make it possible to find precisely the malignant among several hundred components of blood. Accordingly, if you are really afraid of cancer, you need to do research of the main fluid in the body as soon as possible, which in turn will give you a fairly clear picture of the condition.

The most common and applied blood test for oncology is the definition of oncomarkers. These are special proteins or so-called "antigens" that are secreted by malignant cells in the event of an ailment. In addition, due to the availability of modern equipment, conducting such a study will provide some information about the existing tumor. For example, you can determine its size and even the stage of the disease. All oncomarkers are divided into several species, each of which will testify to the defeat of a particular organ. For example, in women, the presence of a high concentration of protein CA125 will indicate the presence of ovarian cancer or the endometrium of the uterus. While an increased amount of CA 15-3 indicates a lesion of the breast with metastases. Thinking about where to take tests for oncology, you should first choose a clinic that will check the presence in the blood of each type of component, indicating the neoplasm.

It is necessary to take into account the possibility of conducting diagnostics at absolutely any stage of the alleged illness. It should be noted that a qualitatively and timely analysis of blood in oncology will allow not only to identify the disease at an early stage of development, but also to get rid of it as quickly as possible. Of course, such a check is not the only one, however, thanks to it, the doctor will be able to assign the further study necessary for accurate diagnosis. In addition, a blood test with oncology will identify possible recurrences of the ailment, which, it would seem, has already receded. Even if the likelihood of recurrence of the disease is negligible, a qualitative study of biochemical material will help to reveal the lowest percentage. At the same time, one should not forget that the detection of the window of markers should be carried out exclusively on an empty stomach, in the supine or sitting position. It is forbidden to drink alcohol a day before taking the test, as well as taking drugs and drugs.
