Estimating cancer risks to a population.
Three important issues impinge on estimating the risk of cancer to a population: (1) How can one use epidemiologic studies on one population to tell us what is likely to happen to other populations? (2) How can one use nonhuman data (i.e., laboratory experiments) to tell us what is likely to happen to humans? (3) What reasonable assumptions can be used to guide the logical extension of informat...
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 کاملEstimating Breast Cancer Risks Using Neural Networks
Breast cancer is one of the most important medical problems. In this paper, we report the results of using neural networks for breast cancer diagnosis. The theoretical advantage is that posterior probabilities of malignancy can be estimated directly, and coupled with resampling techniques such as the bootstrap, distributions of the probabilities can also be obtained. These allow a researcher mu...

متن کاملOn Estimating a De Facto Population and Its Components
Abstract. This paper deals with estimating a population that is largely defined by the fact that its size, composition, and distribution are not readily accessible from census data in the U.S. and the other countries that use the De Jure concept of population. The population in question is based on the De Facto concept, which involves the estimation of people where they are found rather than wh...
