OBJECTIVES We evaluated whether breast self-examination (BSE) influences subsequent mammography participation. METHODS We evaluated associations between BSE and subsequent mammography participation, adjusting for baseline screening behaviors and sociodemographic, health, and lifestyle characteristics, among women aged 40 years and older using data from the longitudinal Canadian National Popul...

The purpose of this study was to evaluate whether screening by clinical breast examination (CBE) in addition to mammography affected participant satisfaction in the National Cancer Screening Program (NCSP). Data were derived from the Quality Evaluation of National Cancer Screening satisfaction survey. This population-based nationwide telephone survey included participants who had been screened ...

Introduction: Breast cancer is the second leading cause of cancer deaths in women today. Currently, mammography is the primary method of early detection. However, research has shown that many cases (10-30%) missed by mammography can be detected using breast MRI (BMRI). BMRI is more difficult to interpret than mammography because it generates significantly more data. Also, there are fewer people...

According to Autier and colleagues, little of the decline in the breast cancer death rate in northern Europe can be attributed to screening mammography. Similar concerns in the United States led its Preventive Services Task Force to endorse the elimination of routine screening in women younger than 50 and the reduction of screening from every year to every two years in older women. The recommen...

SUMMARY Given recent the debate over breast cancer screening that was reignited by the 25-year follow-up data from the Canadian National Breast Screening Study, the Canadian Journal of Surgery commissioned a group of Canadian experts to debate the value of screening mammography. We discuss the Canadian study and summarize the arguments in favour of and against screening mammography for average-...

OBJECTIVE We show with both a clinical case and measurements using the American College of Radiology mammography phantom that some digital mammography acquisition and image display combinations lead to both marked over- and underestimation of lesion sizes on geometrically magnified images. CONCLUSION The results of this study indicate that the accuracy of lesion size measurements in all magni...

BACKGROUND The efficacy of breast cancer screening in women age 40 to 49 years remains controversial. OBJECTIVE To compare breast cancer mortality in 40- to 49-year-old women who received either 1) screening with annual mammography, breast physical examination, and instruction on breast self-examination on 4 or 5 occasions or 2) community care after a single breast physical examination and in...

BACKGROUND The performance of diagnostic mammography for women with signs or symptoms of breast cancer has not been well studied. We evaluated whether age, breast density, self-reported breast lump, and previous mammography influence the performance of diagnostic mammography. METHODS From January 1996 through March 1998, prospective diagnostic mammography data from women aged 25-89 years with...
