Radiation oncology is a medical science that studies the effects of ionizing radiation treatments on cancer cells. Applications made in radio-oncology clinics are studied in two different groups as radiosurgery and radiation therapy. Treatment procedures in both groups are also carried out with radiation. The type of treatment plan to be used for the patient is determined after in-depth examinations and diagnostic tests by multidisciplinary teams of medical specialists and health workers.

​

• Radiosurgical practices in radiation oncology clinics. Radiation surgery is known as radiosurgery. In these applications, malignant tumors of appropriate structure can be removed from the body using certain techniques, as if they had been removed by surgery. As with radiation therapy procedures, radiosurgery aims to treat cancer.

​​

• Stereotactic Radiosurgery (SRS): Cancer cells that have been targeted in stereotactic radiosurgery are coordinated in three dimensions and then destroyed in a single session with a high-dose radiation beam. The use of the procedure accompanied by imaging procedures (IGRT) increases the selectivity for the target tissue and minimizes the damage to healthy tissue.

​​

• Stereotactic Radiation Therapy (SRT): In stereotactic radiation therapy, the target cancerous tissue is destroyed in 3-4 sessions instead of a single session, unlike SRC, which uses lower doses of radiation. With this method, the target tissue can be treated more sensitively and a high level of protection of the healthy tissue can be achieved.a
