Pesticides, common environmental exposures, have been examined in relation to breast cancer primarily in occupational studies or exposure biomarker studies. No known studies have focused on self-reported residential pesticide use. The authors investigated the association between reported lifetime residential pesticide use and breast cancer risk among women living on Long Island, New York. They ...

When assessing the impact of radiation exposure it is common practice to present the final conclusions in terms of excess lifetime cancer risk in a population exposed to a given dose. The present investigation is mainly a methodological study focusing on some of the major issues and uncertainties involved in calculating such excess lifetime risks and related risk projection methods. The age-con...

BACKGROUND Corpus uterine cancer is the most common gynecologic malignancy in Puerto Rico and the United States. METHODS We assessed the lifetime risk of developing and dying of corpus uterine cancer in women living in Puerto Rico (PR) and among Hispanics, non-Hispanic whites (NHW), and non-Hispanic blacks (NHB) in the United States. Data from the PR Central Cancer Registry and the Surveillan...

PURPOSE To quantify the effect of reduced life expectancy on cancer risk by comparing estimated lifetime risks of lung cancer attributable to radiation from commonly used computed tomographic (CT) examinations in patients with and those without cancer or cardiac disease. MATERIALS AND METHODS With the use of clinically determined life tables, reductions in radiation-attributable lung cancer r...

BACKGROUND Tools for estimating population exposures to environmental carcinogens are required to support evidence-based policies to reduce chronic exposures and associated cancers. Our objective was to develop indicators of population exposure to selected environmental carcinogens that can be easily updated over time, and allow comparisons and prioritization between different carcinogens and e...

Prevention offers the most cost-effective long-term strategy for the control of cancer and at least one-third of all malignancies are preventable. A number of strategies have been developed over the last decades to provide opportunities for cancer prevention at different levels: primary prevention by reducing levels of exposure to high risk factors or causative agents, secondary prevention thro...

introduction public transportation system is the perfect solution to organize transportation in the city. this system reduces the demand for private car or taxi area provides economic savings. public transport will not only reduce the use of private vehicles, but it will reduce traffic and air pollution. the public transportation system of buses to be extremist as one of the most efficient publ...

Risk projection methods allow for timely assessment of the potential magnitude of radiation-related cancer risks following low-dose radiation exposures. The estimation of such risks directly through observational studies would generally require infeasibly large studies and long-term follow-up to achieve reasonable statistical power. We developed an online radiation risk assessment tool (RadRAT)...

The study evaluates associated health risks of heavy metals in the soil to inhabitants of two mining areas of Nigeria. For so doing, it collects and analyses nine homogenous soil samples for their lead, copper, cadmium, zinc, and chromium levels, using AAS. The samples are then used to calculate health risks to adults and children. For adult population in Agbaja community, the calculated hazard...
