1. Aspects in mammographic screening : Detection, prediction, recurrence and prognosis
Sammanfattning : Screening mammograms comprising of 32 first round, 10 interval and 32 second round detected cancers and 46 normal were examined by an expert screener, a screening radiologist, a clinical radiologist and a computer-assisted diagnosis (CAD) system. The expert screener, screening radiologist, clinical radiologist and the CAD detected 44, 41, 34 and 37 cancers, respectively, while their respective specificities were 80%, 83%, 100% and 22%.

2. Access to and participation in mammographic screening within a region in Sweden
Sammanfattning : The population-based mammographic screening programme offers every woman in Sweden between 40 and 74 years of age a mammogram with the purpose of early detection of potential breast cancer. The programme is seemingly equal in its setup; however, approximately 20 percent of the women do not participate in the screening. LÄS MER
3. Mammography Screening-Factors affecting Tumour Stage and Outcome
Sammanfattning : The aim of this thesis was to investigate screening mammography in relation to factors affecting tumour stage and outcome. The main focus was on obesity, tumour biology and breast density. We hypothesized that obese and overweight women could benefit more from screening detection than normal weight women. LÄS MER
4. Breast cancer screening in an urban, Swedish population Aspects of non-attendance, interval cancers and over-diagnosis
Sammanfattning : Service screening with mammography was implemented in Sweden in the late 80's, following the results from trials in Sweden and abroad. A high rate of attendance, a high diagnostic accuracy and treatment in accordance with established guidelines are key circumstances for an effective screening programme. LÄS MER
5. Interval cancers, positive predictive value for malignance and other early quality indicators in mammographic screening for breast cancer
Sammanfattning : The study was designed to evaluate early quality indicators in screening for breast cancer. lt comprised, (i) investigations of compliance, recall, referral, cancer detection, and interval cancer rates in the Östergötland screening programme of women aged 40-74 years; (ii) evaluation of the three-stage diagnostic procedure for pre-operative assessment of women with suspicious mammographic findings; (iii) comprehensive analysis of all invasive interval cancers detected; and (iv) investigation into how to reduce the number of interval cancers without a concomitant increase in false positives.
