Breast Cancer Incidence, Mortality and Its Risk Factors among Women Worldwide, 2015

Abstract

Breast cancer is the top cancer in women both in the developed and the developing world.  And is increasing, particularly in developing countries where the majority of cases are diagnosed in late stages as well as by the lack of adequate diagnostic and treatment facilities.

The incidence of breast cancer is increasing in the developing world due to increase life expectancy, increase urbanization and adoption of western lifestyles. Several risk factors for breast cancer have been well documented. However, for the majority of women presenting with breast cancer, it is not possible to identify specific risk factors. Although some risk reduction might be achieved by preventing, these strategies cannot eliminate the majority of breast cancers that develop in low- and middle-income countries where breast cancer is diagnosed in very late stages. This paper reviews the current patterns of breast cancer in worldwide and examines breast cancer risk factors with the intention that knowing they could eventually have an impact in reducing the incidence of breast cancer in the long term.
