The treatment of tumors of various localization and etiology has been one of the most pressing problems of modern medicine all over the world for many years. Every day, every healthy person forms several dozen atypical cells, which the innate immunity can easily deal with. However, when negative environmental factors begin to regularly and aggressively affect the human body, the immune system ceases to cope with its task and a tumor process occurs.
There are many methods of dealing with malignant neoplasms. In some cases, they quite effectively suppress tumor cells, but they often have a toxic effect on the human body.
The main, radical method of treating tumors is surgical treatment. This is a method that allows you to eliminate the underlying tumor. However, it is effective in the early stages of the disease, with an anatomically favorable location of the tumor and the absence of metastases. For further prevention of relapses and metastasis, surgery alone is not enough – complex systemic therapy is required.
One of the most common methods of fighting cancer is radiation therapy. The course of exposure is about two months. During this time, the entire human body is exposed to X-rays. Atypical cells with this effect first stop dividing and then die. But the systemic effects of radiation therapy do not pass without a trace. First of all, rapidly renewing cells suffer, including the epithelium of the skin, mucous membranes, and blood cells. Nausea and vomiting often occur, there may be diarrhea, general health worsens, and the ability to work sharply decreases.
Chemotherapy is a method of fighting atypical cells by exposing them to toxic substances. Such drugs do not have specificity for pathological foci, which means they have the same effect on all organs and tissues. That is why side effects are inevitable: from minor manifestations in the form of hair loss, nausea and vomiting, to serious ones: bleeding, toxic damage to the liver and kidneys, which can lead to death.
Thus, despite the effectiveness of such treatment methods, there is a serious problem of severe complications.
Cancer is a systemic process that affects the entire body. A malignant tumor of an organ or tissue is a symptomatic manifestation of this disease. Guided by this rule, it becomes obvious that oncology requires an integrated approach to treatment. But how can you protect healthy organs and tissues from the effects of aggressive toxic treatments?
This task is successfully performed by complex biotherapy, which combines an antitumor effect with immobilization of the immune, hormonal and neurohumoral systems of the body.
It is no coincidence that it is one of the key methods of treatment in the complex therapy of cancer, successfully complementing other clinical methods.
Photodynamic therapy is based on the use of drugs – photosensitizers (substances that are sensitive to light) and low-intensity (therapeutic) laser radiation with a certain wavelength corresponding to the absorption peak of the photosensitizer. The necessary components for photodynamic therapy are a photosensitizer, which selectively accumulates only in the affected tissues, and light sources with certain physical parameters. Treatment with photodynamic therapy does not produce severe systemic or local complications. And at this time, the development of new drugs continues, the action of which is aimed at eliminating only modified cancer cells.
