Time delay after an abnormal screening mammogram may have a critical impact on tumor size, stage at diagnosis, treatment, prognosis, and survival of subsequent breast cancer. This study was undertaken to evaluate disparities between Latina and non-Hispanic white (NHW) women in time to definitive diagnosis of breast cancer after an abnormal screening mammogram, as well as factors contributing to...

INTRODUCTION Breast cancer is the commonest female cancer in Singapore. It is steadily rising with an incidence of 53.1 cases per 100,000 persons per year among women. Screening for detection of early lesions which are highly curable helps to reduce mortality. METHODS Over three afternoon sessions in December 2003, 224 female patients aged 40-65 years, participated in interviews conducted by ...

PURPOSE To evaluate, by using a computer-aided detection (CAD) program, the nonspecific findings on normal screening mammograms obtained in women in whom breast cancer was later detected at follow-up screening mammography. MATERIALS AND METHODS Four hundred ninety-three mammogram pairs-an initial negative screening mammogram and a subsequently obtained screening mammogram showing cancer-were ...

BACKGROUND Screening mammography is the best method to reduce mortality from breast cancer, yet some breast cancers cannot be detected by mammography. Cancers diagnosed after a negative mammogram are known as interval cancers. This study investigated whether mammographic breast density is related to the risk of interval cancer. METHODS Subjects were selected from women participating in mammog...

Objectives: We evaluated a single free breast cancer screening program for breast cancer rate per 1,000 mammograms and compared it to the national cancer rate. We aimed to determine compliance rate in previously noncompliant women, to determine recall rate, and to find the percentage of diagnostic imaging done as a first test on a previously unscreened population. Methods: A retrospective chart...

BACKGROUND Mammographic density is a strong risk factor for breast cancer. However, whether changes in mammographic density are associated with risk remains unclear. MATERIALS AND METHODS A study of 372 incident breast cancer cases and 713 matched controls was conducted within the Mayo Clinic mammography screening practice. Controls were matched on age, exam date, residence, menopause, interv...

BACKGROUND Access to mammograms, in common with other diagnostic procedures, is strongly conditioned by socioeconomic disparities. Which aspects of inequality affect the odds of undergoing a mammogram, and whether they are the same in different localities, are relevant issues related to the success of health policies. METHODS This study analyzed data from the 2008 PNAD - Brazilian National Ho...

RATIONALE AND OBJECTIVES The wide use of computer technology in education, particularly in mammogram reading, asks for e-learning evaluation. The existing media comparative studies, learner attitude evaluations, and performance tests are problematic. Based on an affordance design model, this study examined an existing e-learning program on mammogram reading. MATERIALS AND METHODS The selectio...

In the past several years there has been tremendous interest in image processing and analysis techniques in mammography. One common approach for detecting abnormalities in mammograms [1, 2] is to use a series of heuristics, e.g. filtering and thresholding, which may include texture analysis to automatically detect abnormalities [3]. These heuristic methods suffer from a lack of robustness when ...

BACKGROUND Women with a history of a false-positive mammogram result may be at increased risk of developing subsequent breast cancer. METHODS Using 1994 to 2009 Breast Cancer Surveillance Consortium data, we included women ages 40 to 74 years with a screening mammogram that resulted in a false-positive with recommendation for additional imaging, false-positive with recommendation for biopsy, ...
