“…Electronic magnification (zooming) is important in the detection of calcification and is helpful in the initial assessment of digital mammograms. However, zooming function has been shown to improve the performance of only some observers . Once calcification that is not obviously benign is detected, it is the policy of the Clinic to use spot compression and geometric magnification (with its higher spatial resolution) to further assess the morphology and the extent of the microcalcification.…”

“…Mortality rates peak in low-middle-income (LMICs) and low-income countries (LICs) in Latin America and Caribbean (Barbados, Bahamas), Africa (Jamaica, Nigeria, Namibia, Ethiopia), and Asian Oceania (Fiji, Papua New Guinea, Malaysia, Thailand, Vietnam) with the range from 20 to 42 deaths per 100,000 women (age-standardized) (1). The high incidence of breast cancer in high-income countries has been described as reflecting the increase in the accessibility of mammography screening programs and the prevalence of well-known breast cancer risk factors (e.g sedentary lifestyles, late reproductive records and being overweight after menopause) (12)(13)(14)(15)(16)(17), while high mortality rates in LMICs and LICs were found to be associated with lack of access to quality health care and treatment (18)(19)(20)(21)(22).…”

The development of screening mammography over 30 years has remarkedly reduced breast cancer–associated mortality by 20%-30% through detection of small cancer lesions at early stages. Yet breast screening programmes may function differently in each nation depending on the incidence rate, national legislation, local health infrastructure and training opportunities including feedback on performance. Mammography has been the frontline breast cancer screening tool for several decades; however, it is estimated that there are 15% to 35% of cancers missed on screening which are owing to perceptual and decision-making errors by radiologists and other readers. Furthermore, mammography screening is not available in all countries and the increased speed in the number of new breast cancer cases among less developed countries exceeds that of the developed world in recent decades. Studies conducted through the BreastScreen Reader Assessment Strategy (BREAST) training tools for breast screening readers have documented benchmarking and significant variation in diagnostic performances in screening mammogram test sets in different countries. The performance of the radiologists from less well-established breast screening countries such as China, Mongolia and Vietnam were significant lower in detecting early-stage cancers than radiologists from developed countries such as Australia, USA, Singapore, Italy. Differences in breast features and cancer presentations, discrepancies in the level of experiences in reading screening mammograms, the availability of high-quality national breast screening program and breast image interpretation training courses between developed and less developed countries are likely to have impact on the variation of readers’ performances. Hence dedicated education training programs with the ability to tailor to different reader cohorts and different population presentations are suggested to ameliorate challenges in exposure to a range of cancer cases and improve the interpretation skills of local radiologists. Findings from this review provide a good understanding of the radiologist’ performances and their improvement using the education interventions, primarily the BREAST program, which has been deployed in a large range of developing and developed countries in the last decade. Self-testing and immediate feedback loops have been shown to have important implications for benchmarking and improving the diagnostic accuracy in radiology worldwide for better breast cancer control.
