The Role of Particle Therapy in the Risk of Radio-induced Second Tumors: A Review of the Literature

One of the most important late side-effects of radiation therapy is the development of radiation-induced secondary malignancies. In the last years, this topic has significantly influenced treatment decision-making as the number of long-term cancer survivors has significantly increased with advances in treatment modalities.

In this review article we summarize the current knowledge about treatment-related secondary cancers with a particular attention to hadrontherapy.
