..Both factors likely contributed to the observed trends, and the role of each may vary across age groups...

..The aim of this study was to examine the sensitivity and specificity of screening mammography as performed in Vermont, USA, and Norway...

..To estimate the cumulative risk of a false-positive screening result in European mammographic screening programmes, and examine the rates and procedures of further assessment...

..More research is required to determine whether these differences in stage-specific incidences among invited participants and non-participants are associated with differences in mortality rates...

..This study analyzes the stage distribution of invasive breast cancers diagnosed in the pre-screening and screening period, and evaluates the overall mortality in women aged 55-74 in the pilot and non-pilot counties of the NBCSP...

..Physical activity may affect hormonal concentrations that may have bearing on the risk of breast cancer. The aim of this study was to investigate whether physical activity affects this risk...

..Based on the results, we anticipate a future mortality reduction from breast cancer in women invited to the NBCSP...

..The screening period is divided into those invited versus those not invited to the screening program, and those exposed (participants) versus those not exposed to the program (non-participants)...

..Interval cancers are considered a shortcoming in screening mammography due to less favorable prognostic tumor characteristics compared to screening-detected cancers and consequently a lower chance of survival from the disease...

..To analyze discordant and concordant screening-detected breast cancers in a nationwide population-based screening program by using independent double reading with consensus...

..To compare interval breast cancer rates (ICR) between a biennial organized screening programme in Norway and annual opportunistic screening in North Carolina (NC) for different conceptualizations of interval cancer...

..The risk of breast cancer is higher in women who respond only after a reminder letter, indicating that the value of sending a reminder should be assessed in the light of these results, as well as by the increase in the attendance rate...

..To retrospectively investigate whether different review designs have an influence on the estimate of missed interval cancer in a population-based breast cancer screening program...

..To survey factors of importance for attendance in the Norwegian Breast Cancer Screening Program (NBCSP)...

..Interval cancer was associated with dense breasts and use of HRT. Screening programs must keep these associations in focus...

..We examined how these differences affect early detection of breast cancer by comparing performance measures and histopathologic outcomes in women undergoing opportunistic screening in Vermont and organized screening in Norway...

..The process indicators achieved in the NBCSP are promising as regards future mortality reduction. The incidence of interval cancer 13-24 months after screening is higher than recommended in the European guidelines...

..The aim of this study was to investigate the incidence according to grade distribution, age, and implementation of a population-based screening programme...

..A secondary objective was to estimate the cumulative risk of undergoing fine-needle aspiration cytology, core needle biopsy, and open biopsy with benign morphology in the same group of women...

....

..The increased risk of interval cancer, which may partly be due to decreased sensitivity of mammograms in HT users, remains a challenge in breast cancer screening programs...

..Such an implementation is expected to give an initial increased incidence followed by a decrease. We here present general and stage-specific incidences of breast cancer by age groups, in the first 9 counties that implemented the NBCSP...

..Human papillomavirus and hormonal contraceptives may be risk factors for cervical precancer and malignant breast tumours...

....

..To prospectively compare performance indicators at screen-film mammography (SFM) and full-field digital mammography (FFDM) in a population-based screening program...

..In conclusion FFDM had a significantly higher detection rate for DCIS than SFM. For invasive cancers no difference was seen. FFDM also had a significantly higher PPV and a significantly lower technical recall rate...

..The study showed that the population-based breast cancer mortality trend is too crude a measure to detect the effect of screening on breast cancer mortality during the first years after the start of a programme...
