Comparison of Survival Rates

The global rise in breast cancer incidence rates is observed to be about 0.5% annually since 1990. In contrast, Chinese cancer registries report rapid increasing annual incidence rates of 3-4% even in the absence of population-based breast cancer screening (Parkin et al., 2005). In GLOBOCAN 2012, the estimated rate of increase in ASR being 2.5% per year seems to be slowing down (Ferlay et al., 2013). Breast cancer was estimated to cause almost 459,000 female death in 2008 and around 522,000 in 2012 worldwide with an age-standardized rate of 13.9 deaths per 100,000 and the 2012, the rate is expected to decline to 12.9 (Ferlay et al., 2010; 2013), thus in contrast, a longer survival time. Despite the decreasing mortality rate of breast cancer, it remains the leading cause of cancer-related mortality amongst females internationally, and accounts for almost 14% of all cancer deaths. Breast cancer mortality among Chinese women has been decreasing a lot but, in contrast, the incidence has doubled during the past 30 years (Parkin et al., 2005;
