Abstract
The objective of this study was to investigate the recent incidence and mortality trends for breast cancer in Mexican females. Data between 2000 and 2010 from the Department of Epidemiology of the Ministry of Health, and International Agency for Research on Cancer (IARC) were analyzed. Age-standardized rates (ASRs) and annual percent changes (APCs) were calculated. The absolute incidence and mortality rates of breast cancer increased: 3,726 and 4,615 in 2000 to 8,545 and 4,966 in 2010, respectively. Incidence increased over time in all age groups tested, the 60-64 age group had the highest ASR (57.4 per 100,000 women in 2010), while the 20-44 age group had the lowest ASR (12.3 in 2010). The results show that incidence of breast cancer has increased in Mexico during last one decade, especially among older women, while the downturn observed in mortality mainly reflects improved survival as a result of earlier diagnosis and better cancer treatment.
Highlights
Breast cancer is the most frequently diagnosed cancer and the leading global cause of cancer death in women, accounting for 23% of cancer diagnoses (1.38 million women) and 14% of cancer deaths (458 000 women) each year
The results show that incidence of breast cancer has increased in Mexico during last one decade, especially among older women, while the downturn observed in mortality mainly reflects improved survival as a result of earlier diagnosis and better cancer treatment
In order to better gauge and interpret the changing breast cancer incidence and mortality in Mexico, we studied the trends in incidence and mortality rates from 2000 to 2010, for focus on areas of weaknesses and future avenues to improve breast-cancer care in Mexico
Summary
Breast cancer is the most frequently diagnosed cancer and the leading global cause of cancer death in women, accounting for 23% of cancer diagnoses (1.38 million women) and 14% of cancer deaths (458 000 women) each year. Breast cancer has a markedly higher incidence in developed countries, half of new breast cancer diagnoses and an estimated 60% of breast cancer deaths are thought to occur in the developing world (Jemal et al, 2011). The incidence and mortality rate in developing countries are even higher because of limited medical infrastructure and awareness (Taghavi et al, 2012; Shaukat et al, 2013). Breast cancer can be detected in its early stages through breast self-examination, clinical breast examination and mammography screening. Mammography screening has led to a substantial reduction -estimated to be about 15%- in breast cancer mortality (Ki-Bong et al, 2013)
