What is oncology? This term refers to the field of medicine that fights against formations in the human body. It is about her that will be discussed in this article. We will tell you more about the deadly disease and its manifestations.
What do oncologists do?
Specialists in this field of medicine are developing new methods for detecting the presence of cancer cells in the organs and tissues of the human body, diagnosing the disease, combating low-grade neoplasms and monitoring the course of the patient’s disease. 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:
In the first case, proliferation occurs slowly, painlessly and is absolutely harmless to human health, in the second case, rapid growth and the absence of its own membrane of formation are observed, which leads to damage to nearby tissues and organs. Altered (cancerous) cells can move through the body through the blood, thereby infecting other organs. They spread foci throughout the body. A tumor can grow into 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 is a tumor formed by the tissues of the epithelium, covering almost all organs of the human body. An infected cell with a changed structure leads to neoplasm. Why do mutations occur in the structure? There are several versions:
- Radiation, ultraviolet.
- Carcinogens.
- Viruses.
- Heredity.
Sarcoma is a tumor formed by connective tissue. It can affect any organ (including bones, muscles, nerve tissue, and so on).
Oncology. Stages
The disease progresses rather quickly, but initially it is rather difficult to determine its presence. Even based on 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 with it die. At this stage, the tumor reaches its maximum size and grows into other tissues and organs, forming metastases.
What is oncology? Sentence or can it be cured?
Medicine today has achieved quite good successes in the field of oncology, but there is still no cure for cancer damage to the body. 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 drugs;
- antibodies;
- specialized vaccines and so on.
In this article we talked about what oncology is and highlighted the main provisions concerning it. Be healthy! And regularly undergo a medical examination.
