Mammographic Density and the Risk and Detection of Breast Cancer

Abstract: Extensive mammographic density is strongly associated with the risk of breast cancer detected by screening or between screening tests. A substantial fraction of breast cancers can be attributed to this risk factor.

“…In Korea, mammography is implemented for breast cancer screening with controversy in cost-effectiveness (Kang et al, 2013;Yoo et al, 2013). Mammography has well recognized limitations, such as reduced sensitivity of both screening and diagnostic mammography in dense breast tissue by as much as 50% compared with fatty breast tissue (Kolb et al, 2002;Berg et al, 2004;Boyd et al, 2007). The sensitivity is lower among women younger than 50 years and extremely dense breast tissue carries a higher risk for breast cancer: up to an 18-fold increase in interval cancer compared with fatty breast tissue (Boyd et al, 2007).…”

“…Dessa forma, pode-se supor que a menor atividade enzimática decorrente do genótipo nulo dos referidos genes poderia estar associada ao aumento da densidade mamária, o que se traduziria principalmente por padrão mamográfico denso [16][17][18] . Também é consenso atual que a densidade mamária é um importante fator de risco para câncer de mama 19 .…”

Também é consenso atual que a densidade mamária é um importante fator de risco para câncer de mama 19 .Desta forma, este estudo objetivou determinar a freqüência das referidas deleções numa população de mulheres portadoras de CM esporádico em comparação com mulheres sem câncer e avaliar as características mamográficas dos CM cujas mulheres apresentam as deleções dos genes GSTM1 e GSTT1 e compará-las às não portadoras das referidas deleções. …”

“…An interesting potential explanation is that progestin exposure promotes the progression of pre-existing lesions to invasive cancer, which is in line with Nielsen's findings 6 . Finally, high mammographical breast density, one of the strongest risk factors for breast cancer 29,30 was correlated with progestin intake [31][32][33] .…”
