Description
Summary:The median age at diagnosis of breast cancer was 54 years.6 Due to different tumour characteristics and the overall smaller size and denser fibroglandular tissue of Asian women's breasts, local epidemiology and clinical studies are important to facilitate our understanding of this common disease in Hong Kong. [...]there was a trend towards increased detection of smaller tumours of [lesser than]2 cm in the screen-detected group, likely explained by the advances in radiological imaging technology in mammogram and ultrasound. [...]the mean age at first diagnosis of breast cancer was 50 years (range, 24-92 years) and median age of 40 to 49 years in both the self-detected and screen-detected groups in this study. Newer technology such as digital breast tomosynthesis may provide higher sensitivity and increase cancer detection rate compared with digital mammography because of its ability to remove overlapping glandular tissue, the main reason for both false-positive and -negative results with traditional mammography.10 11 12 13 14 Although tomosynthesis requires breast compression similar to mammogram, the compression force may be lower without affecting image quality.14 Further studies would be helpful to determine whether the benefits of the MammoPad used by Chan et al8 could have further benefit in tomosynthesis.
