What is oncology? This term indicates the area of ​​medicine, which is fighting the formations in the human body. It will be discussed in this article. We will tell you in more detail about the deadly disease and its manifestations.

What do oncologists do?

Specialists in this field of medicine developnew methods for detecting the presence of cancer cells in the organs and tissues of the human body, diagnose the disease, fight with malignant neoplasms, and track the course of the patient's illness. What is oncology, a tumor? This is a significant increase in tissue with a changed structure of the structure of cells.

Cancer, oncology. Types of tumors

Tumors are divided into two categories:

  • benign;
  • malignant.

In the first case, the growth is slow,painless and absolutely harmless to human health, in the second case there is a rapid growth and the lack of its own shell of education, which leads to the destruction of nearby tissues and organs. Changed (cancerous) cells can move through the body through the blood, thereby infecting other organs. They carry out foci throughout the body. The tumor can sprout into the lymph nodes, blood vessels and form metastases, the presence of which significantly reduces the likelihood of getting rid of the disease.

Malignant neoplasms are also divided into two groups:

  • cancer;
  • sarcoma.

Cancer is a tumor formed by epithelial tissues,covering almost all organs of the human body. An infected cell with a changed structure leads to a neoplasm. Why do mutations occur in the structure? There are several versions:

  1. Radiation, ultraviolet.
  2. Carcinogens.
  3. Viruses.
  4. Heredity.

Sarcoma is a tumor formed by a connective tissue. It can affect any organ (including bones, muscles, nervous tissue and so on).

Oncology. Stages of

The disease progresses rather quickly, howeverinitially to determine its presence is rather difficult. Even on the basis of analyzes and other procedures. Depending on the type of tumor (or rather, the organ or tissue on which it is located) its development can be conditionally divided into stages. The fourth is considered the most severe form of the disease and more than 90% of patients who have it die. At this stage, the tumor reaches its maximum size and sprouts into other tissues and organs, forming metastases.

Medicine today has made quite good progress inthe field of oncology, but there is still no cure for the defeat of the body by cancer cells. Depending on the severity of the disease and the degree of infection, various types of treatment and their combinations can be used:

  • chemotherapy;
  • radiation therapy;
  • surgical intervention;
  • antibiotics;
  • hormonal means;
  • antibodies;
  • specialized vaccines and so on.

In this article, we told about what oncology is and highlighted the main provisions concerning it. Be healthy! And regularly undergo a medical examination.
