The process of cancer treatment is very long and complicated. A single medicine against cancer does not exist yet, but the combination of various drugs in oncology allows to achieve inhibition of tumor growth, removal of pain syndrome and general improvement of the patient’s condition.
The main task of any medicine is to destroy the tumor cells. In some cases, for example, in the last stages of the disease, cancer cannot be destroyed, but it can be stopped further development. In this regard, drugs for cancer should, as a minimum, slow down the growth and reproduction of malignant cells.
Modern drugs in the treatment of cancer solve several problems. Therefore they are appointed more often in a complex. Some cancer drugs destroy the affected cells, others stop their growth and prevent the emergence of new cancer cells. In the late stages of active use of painkillers, as well as drugs that themselves do not affect the growth of the tumor, but improve the overall condition of the person, removing unpleasant symptoms.
A relatively recently targeted group of drugs has been developed. They got their name from the English word “target”, which means “goal.” These drugs from oncology affect only the affected cells, not affecting the healthy. Target drugs block the access of oxygen to cancer cells, and the latter dies. This cancer drug is considered much safer than traditional chemotherapeutic agents; it gives good results even in severe patients in an extremely weakened state.
Today there are also interesting and promising studies in the field of developing a vaccine against cancer. This is one of the newest biotherapeutic methods. Its essence consists in isolating antigens from the tumor and introducing them into the patient’s body. This sequence of actions allows you to “teach” immune cells to recognize oncogenes. Thus, the immune system itself can detect cancer cells in time and destroy them.
