Methods for detecting cancer cells in the human body

Cancer is one of the most serious diseases of this time. Now the number of people who have fallen ill many times exceeds the level of the past decades. This phenomenon scientists associated with the growth of adverse factors that affect people in modern society. The study of cancer cells and the development of methods to combat them is engaged in oncology. During her research she accumulated a rich experience in diagnosing this disease.

Diagnosis and treatment problems

When the body is infected with cancer, metastases form in it. When the disease progresses, the localization of tumor centers in the places where they were originally detected is disrupted. Cancer cells are able to separate from such foci, spread throughout the body and form new metastases. And they have tremendous vitality. Only one such mobile cell can cause large cancers. The difficulty of treatment lies in the fact that by destroying metastasis, it can not be guaranteed that there are no more cancer cells left in the body. The patient in any case needs to undergo a course of chemotherapy.

Blood test

Medicine came very close to resolving this problem. Oncologists have received a method that allows the marking of cancer cells. The tagged object is easy to detect. Such an analysis makes it possible to detect cancer at early stages of development. It is also used to control the patient's condition during treatment and helps to adjust the number of necessary procedures as accurately as possible. This significantly reduces the harm caused to the body by anticancer therapy. In addition, the presence of tumor cells can be established by the products of their vital activity in the patient's blood. To do this, the cancer cells are analyzed. The price of this procedure varies from 700 rubles to 2 thousand (the cost depends on the type of oncomarker).

Use of radioisotopes in diagnosis

To detect signs of cancer, the most advanced technologies have been applied. A radioisotope study can reveal a pathology when there is still no obvious symptomatology. It is recommended to people at risk. These are those patients in whose family there were already cancer patients.

Positron Emission Tomography

This study relates to modern methods of accurate diagnosis. It not only makes possible the detection of cancer cells in the early stages of the disease, but also allows you to trace their movement in the human body. On the basis of PET, the doctor is able to guess which tissues metastases spread and start prophylaxis in time.

Prediction of treatment outcomes

The favorable outcome of treatment directly depends on the therapy. If the medical intervention occurred early in the development of cancer, then there are great chances for a successful recovery. Among such patients, the number of winners of the disease and those who returned to a normal life is 70-95%.
