Cancer is an important health and life problem with an increasing prevalence.The diagnosis and treatment of cancer should be carried out in a multidisciplinary manner with the cooperation of many specialties.Medical Oncology, one of these specialties, deals with chemotherapy applications, which means the treatment of cancer with drugs.Medical oncology is a branch of science that covers not only the treatment of patients with cancer, but also cancer prevention, screening and early diagnosis.In other words, every stage of cancer is of interest to medical oncology.In medical oncology departments, chemotherapies, targeted smart drugs and molecules, hormonotherapy, immunotherapies and biological therapies are used in cancer treatment.Unlike conventional chemotherapies, smart drugs, which aim to provide comfort today, are applied individually.While chemotherapy is used to shrink the tumor before surgery or for preventive purposes after surgery, it can also be preferred before or after radiotherapy, which is one of the local treatment methods, or both together.
Radiation oncology is the unit that studies the effects of all types of radiation therapy using ionizing radiation on cancer cells and tumors and conducts research in this field.The treatment uses a special type of energy called radiation, which is carried by waves or particles. Radiation oncology treats cancer patients using two methods called radiation surgery and radiotherapy. Radiotherapy can be administered immediately after diagnosis, or in combination with chemotherapy or after surgery. Radiotherapy, also called beam therapy, is among the most innovative and modern treatment methods for curing cancer and relieving symptoms. Radiation therapy applied in the Department of Radiation Oncology (Radiotherapy) is one of the most important and successful treatment methods for cancer.
The high doses of radiation given during radiotherapy have the ability to destroy cancer cells or prevent them from dividing and multiplying. Radiotherapy is much more effective on rapidly dividing and multiplying cancer cells than on normal cells. On the other hand, the recovery of healthy cells is much faster during treatment with this method. For this reason, during the planning phase of radiotherapy treatment, the necessary details and drawings are created to minimize the exposure of normal cells to radiation and the treatment is applied in a targeted manner.
