Background: Environmental ionizing radiation has been associated with increased cancer risk by several studies.  The Brazilian city of Poços de Caldas, MG, seats on a huge deposit of uranium, which was until recently mined.  We performed a retrospective analysis of  310 cases of patients with breast cancer, who were exposed for at least ten years to different levels of ion...

Background: Cardiopulmonary resuscitation (CPR) is a medical emergency intervention aimed at ending life-threatening cardiovascular arrest as quickly possible. However, the ethics of starting CPR in patients who have incurable and terminal disease matter controversy. This ethical dilemma affects cancer particular, they are often suffering from advanced palliative situation. Few data yet availab...

The aim here was to analyze the annual prevalence of breast cancer in Goiânia over a 15-year period. DESIGN AND SETTING This was a cross-sectional study on women with breast cancer diagnosed in Goiânia, Go...

A comparative analysis of cancer prevalence in France, Spain and Italy is presented as part of the EUROPREVAL project. The three countries are culturally and sociologically relatively homogeneous compared with Europe as a whole. However, in all three countries, the cancer registries (CRs) providing the data for prevalence calculation cover only small fractions of the populations, and have been ...

BACKGROUND Estimating the incidence of medical conditions using claims data often requires constructing a prevalence period that predates an event of interest, for instance the diagnosis of cancer, to exclude those with pre-existing conditions from the incidence risk set. Those conditions missed during the prevalence period may be misclassified as incident conditions (false positives) after the...

background: although breast cancer imposes a considerable economic burden on high-income countries, there is limited knowledge about its economic burden in low- and middle-income countries (lmcs), including iran. in this study, we estimated the economic burden of breast cancer in iran in 2010. methods: we used the prevalence-based approach and estimated the direct and indirect costs of all brea...

Background The prevalence of prescribed drugs in survivors colorectal cancer (CRC) was evaluated. Methods Data from the Cancer Registry Norway were linked to Norwegian Prescription Database for a study population 3.52 million individuals. Prevalence ratios (PRs) with 95% confidence intervals (CIs) CRC-survivors compared cancer-free population, estimated by log-binomial regression, adjusting age...
