Epidemiology of radiation-induced cancer.
The epidemiology of radiation-induced cancer is important for theoretical and practical insights that these studies give to human cancer in general and because we have more evidence from radiation-exposed populations than for any other environmental carcinogen. On theoretical and experimental grounds, the linear no-threshold dose-response relationship is a reasonable basis for extrapolating eff...
متن کاملEstimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography
Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...
متن کاملRadiation-induced myocardial perfusion abnormalities in breast cancer patients following external beam radiation therapy
Objective(s): Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer. Methods: To minimize potential confounding fact...
متن کاملRadiosensitizing effects of melatonin on radiation induced chromosomal aberration in G2-lymphocytes of breast cancer patients
Background: Radiotherapy is regarded as a standard treatment modality in breast cancer (BC). Radiation causes cellular damage both in cancer and normal cells by inducing DNA-damage and chromosomal aberrations (CA). Different agents were used for ameliorating effects of radiation, mainly antioxidants such as melatonin. Melatonin shows oncostatic properties on human BC. The aim of this study was ...
متن کاملRadiation risks in perspective: radiation-induced cancer among cancer risks.
The majority of the public in industrial countries believes that pollution and low doses of radiation are threats to good health. As a matter of fact, when these putative risks are compared to those originating from lifestyle, they appear very small. In particular, the risks associated with low doses of irradiation, even when they are assessed with the most pessimistic models, appear extremely ...
