Radiotherapy remains an important treatment modality for patients with chest malignancies; this is particularly true in patients with breast cancer and Hodgkin lymphoma as well as lung, esophageal, and other mediastinal tumors. More than half of patients with these conditions receive radiotherapy at some point. With the development of new treatment modalities, we are witnessing an improvement of overall survival requiring carefully watching of acute and chronic toxicity of radiation therapy. The challenge is not to ignore radiotherapy's side effects in order to explore and prevent them in the future. Strategies for optimizing thoracic radiotherapy and the advent of innovative techniques may represent an encouraging way to decrease thoracic toxicities. We reviewed the literature to identify these cases of toxicity, which are sometimes forgotten, and others, which have recently been described but remain poorly known.
