cancer–induced diagnostic and therapeutic interventions

the purpose of the study was to analyze facts and mechanisms of the development of second malignancies after radiodiagnostic and radiotherapy procedures as well as after different medicamental treatments. the search for relevant articles published over the last 6 years was carried out using medline, elibrary, pubmed databases, and 34 publications were included in this review. the risk of second malignancies from ct scans and radiation therapy is increased by 1.5–3 times in cancer patients. some drugs for treatment of chronic non-oncology diseases and many chemotherapeutic agents possess high carcinogenic potential in longtime period. invasive diagnostic and treatment methods, especially organ transplantations, have protumorogenic effects. some of the diagnostic and treatment methods used in oncology should be considered as «inevitable oncoiatrogenic». applications of these methods require reasonable limitations.
