Radiotherapy is one of the main methods of cancer treatment alone or in combination with chemotherapy. It is applied in about 60% of oncological patients. However, in spite of its clinical usefulness, radiotherapy is associated with a high risk of radiation-induced side effects, including dermatitis, enteritis, cystitis, pericarditis, pneumonia or depression, sexual function disorders, cardiomiopathy, coronary heart disease, anomalies of heart valves and development of second malignant tumor. The early diagnosis and proper treatment of radiation-induced side effects have a major impact on patients` quality of life and future prognosis. Radiation reactions can be categorized as acute or late, occurring before and after six months after radiotherapy. Among the most common acute reactions there were observed: skin rash, mucositis, nausea, vomiting, fever and radiation pneumonitis. Within reference to the late complications, we distinguish for instance fibrosis of organs, a radiation necrosis of bone, ulcers, fistulas, sexual dysfunction and the development of second malignant carcinomas.
