The possibility of radiation therapy during pregnancy remains a subject of discussion, in most cases, specialists try to avoid the use of radiation therapy in a pregnant woman. Currently, there is insufficient data confirming the safety of intrauterine radiation even with the use of modern methods of radiation therapy. 

The purpose of this literature review is to summarize current clinical data on the appropriateness of the use and clinical results of the use of radiation therapy for the treatment of the most commonly diagnosed tumors in pregnant women.

Based on the literature data, it can be said that the possibility of using radiation therapy in the treatment of oncological diseases in pregnant women depends on the localization of the tumor, gestational age, the estimated total focal dose, the size of the irradiation field, the distance from the irradiation field to the fetus, the preferences of the patient.

Keywords: radiation therapy, pregnancy
