What is oncology?

Many people have heard about such concepts as oncology andoncological diseases. In this article we will tell you in detail about what is oncology, let's talk about possible causes of oncological diseases.

Also in the article it is said about the prevention and the methods of treatment of oncological diseases.

The concept of oncology and oncological diseases

Oncological diseases are characterized bydevelopment of malignant and benign tumors. Malignant tumors should be understood as those that are prone to growth, pose a threat to the body and have the ability to release metastases.

Oncology is an area of medicine thatcombines knowledge about cancerous tumors, as well as benign tumors, and studies the behavior of cells involved in their formation, determines the presence in the body of a developing malignant tumor.

Note that cancer cells multiply in the same way as cells of any other organs do.

Causes of cancer

At the moment, medicine is actively studyingcauses that can provoke the growth of malignant tumors in the human body. One of the known reasons provoking oncological diseases are:

The impact of radiation, as well as radio waves.
The impact of carcinogens that enter the human body.
Smoking and eating food containing various flavors, including dyes.

The main cause of development of cancer tumors is considered an imbalance of the body, namely weakening of protective systems.

Cancer Prevention

It is known that good preventionOncological diseases is proper nutrition and exercise. Scientists claim that obesity, as well as a sedentary lifestyle, can increase the development of breast cancer and colon cancer. The American Institute of Research cites statistics according to which 30 percent of people who support a diet suffer from bowel cancer less often. In particular, for the prevention of cancer it is recommended to consume vegetables and fruits, especially beans, whole grains.
A great influence on the body has a sleep mode. The correct sleep regimen not only helps to strengthen human immunity, but also improves its performance against cancer cells. So far, this mechanism has not been fully understood, therefore it is difficult to say exactly how our body is fighting cancer. However, the fact that sleep has a positive effect on health and that people who comply with the sleep regime suffer from cancer much less often is a scientific fact.
The most important way to prevent cancer isregular medical examination. This preventive measure is really capable of protecting a person from the development of cancer. Doctors recommend taking swabs starting from the 21st year of life. This method of preventing early detection of cancer is now the best.

It should also pay attention to the fact that the causes of cancer can be due to heredity.

Methods of fighting cancer

In the framework of this article, we will not considerin detail all ways of fighting with cancer, but we will stop at the most popular ones. These include radiation therapy, chemotherapy and a gamma knife.

Radiation therapy uses in its technique irradiation with X-rays, which kill cancer cells. Healthy cells are not exposed to radiation.
Chemotherapy uses a variety of drugs that suppress the activity of cancer cells and ultimately destroy the tumor.
Finally, the gamma knife allowsCancer removal by surgical intervention. This tool is a concentration of energy that is focused with a lens system at a single point. Thus, it is possible to quickly and with minimal risks remove even very difficult operable tumor.

There is also a method of conventional surgery, which is used in cases where the tumor can be easily removed.
