Worldwide, breast cancer is one of the most common causes of death among women. Undoubtedly, early detection of breast cancer is one of the best ways to manage and treat the disease. According to literature, Mammography and Clinical breast exams are known to be some of the best methods in early detection of breast cancer. Hence information on these two detection methods is very important for planning health policies. This study therefore aimed at reviewing the literature on breast cancer as well as examining the literature on two breast cancer detection methods and their effectiveness. Statistics show that early detection is a primary necessity in the treatment of breast cancer among women. It was also found out that mammography as being the most recommended form of detection, is mostly not available at remote areas in developing countries leading to the increased risk of deaths and hence the greater mortality in these areas. Inexperience and luck of professional know-how have been found to also contribute to the upsurge of cases at developing regions. The review recommends that stakeholders and governmental bodies should help equip such areas with mammography equipment, professional knowledge on its usage. The study also, recommends that further studies be conducted to find out the relationship between various screening methods and age groups to clarify the issue of false positives and false negatives. Also, studies should be conducted on the knowledge and usage of mammographic screening in rural areas of developing centuries.
