Background to the study
Breast cancer is the commonest cancer as it continues to remain the most lethal malignancy in women across the world (Doshi, Reddy, Karunakar & Kulkarani, 2012). It constitutes a major public health issue globally with over one million new cases diagnosed annually, resulting in over 400,000 annual deaths and about 4.4 million women living with the disease (Globocan, 2008; Ganiy and Ganiyu, 2012). Breast cancer is the leading cancer among women but it can also appear in men (Tara, Agrawal & Agrawal, 2008). Although breast cancer is 100 times more common in women than in men, although men tend to have poorer outcomes due to delay in diagnosis (Fasoranti, 2010).
Although breast cancer incidence rates are higher in industrialized countries, recent trends show that the largest increase in risk is occurring in developing countries. There is thus a geographical variation in the incidence of breast cancer with higher incidence in Europe and America compared to Asia and Africa (Otunne, 2008). According to Beiki, Hall, Ekbom and Moradi (2012), the incidence ranks highest in high income countries, with the exception of Japan. In Canada, for example, 19,000 new cases are diagnosed each year and 5, 300 Canadian women die from the diseases annually.
Breast cancer is now the commonest cancer affecting women in Nigeria. In Nigeria, the number of women at risk of breast cancer increased steadily from approximately 24.5 million in 1990 to approximately 40 million in 2010 and is projected to rise to over 50 million by 2020 (Akarolo- Anthony, Ogundiran & Adebamowo, 2010). Statistics from the Ministry of Health Nigeria showed that breast cancer had risen at least four times over the decade and accounted for 40 percent of women cancers (Onyebuchi, 2012). In the present scenario, roughly 1 in 26 women are expected to be diagnosed with breast cancer in their life time, majority of cases occurring in pre-menopausal women (Dosh et al, 2010).
According to Salaudeen, Akande and Musa (2009) studies from various ethnic populations have reported the demographic profile of breast cancer especially from the Western and Northern parts of the country. A review of breast biopsies in the Lagos University Teaching Hospital showed 34 percent of all breast biopsies done over a 10-year period to be malignant. They also asserted that a report from Zaria described the mean age of presentation of breast cancer as 42 years with 30 percent occurring in women less than 25 years of age. Furthermore, at University College Hospital, Ibadan, 74 percent of breast cancer patients were pre-menopausal. A ten year review of breast cancer in Eastern Nigeria revealed that patients with breast cancer constituted 30 percent of all patients with breast disease and that 69 percent of these patients were pre-menopausal (Oluwatosin, 2010).
More so, majority of women present with advanced stages of the disease at which time little or no benefits is derived from any form of therapy. The 5- year survival rate of breast cancer is over 85% with early detection whereas later detection decreased the survival rate to 56% (Dosh et al, 2010; Fasoranti, 2010). The low survival rates of breast cancer in less developed countries can be attributed to lack of early detection as well as inadequate diagnosis and treatment facilities. Oluwatosin (2012) asserted that late presentation of breast cancer patients suggests that women in Nigeria have poor knowledge of the disease. Chiejina (2011) also noted that what is more worrisome in a country like Nigeria with over 140 million people is that the detection of the disease is usually late. For women to present early, they need to be “Breast aware” and must be able to recognize symptoms of breast cancer through routine practice. Late presentation of patients at advanced stages is thus the cause of breast cancer death in Nigerian women, as 80 percent of breast cancer patients in Nigeria are said to die because of late detection (Otunne, 2008)
In an environment where late presentation is predominant there is an urgent need for awareness of breast cancer and its early detection measures. Recommended preventive techniques to reduce breast cancer mortality and morbidity include breast self examination, clinical breast examination and mammography (Doshi et al, 2012). Early diagnosis has a positive effect on the prognosis as well as limits the development of complications and disability (Gwarzo et al, 2009). Changes in the early detection guidelines of the American Cancer Society now recommend that women, beginning in their early 20s should be told about the benefits and limitations of breast self examination. They also recommend that BSE be performed monthly beginning at the age of 20 years and women should undergo a clinical breast examination annually beginning at the age of eighteen years (Salaudeen, Akande, & Musa, 2009). It is an option for women and it is a woman’s best weapon in the fight against breast cancer.This is especially so since nearly 70% of all breast cancer are found through breast self examination and with early detection, quality of life is increased (Gwarzo et al, 2009) and the five year survival rate is 98% (National breast Cancer Foundation, 2012).
An increased awareness among women in general on BSE as a means of detecting breast cancer would most likely result in a high number of women practicing it. If there is increased awareness and improvement in the capacity of women to understand themselves, it will enable them seek medical attention early enough. Awareness can be created by health workers such as nurses and doctors. Newspapers, journals and the internet are also sources where one can read articles written on BSE (Cosgrave, 2009). According to Oluwatosin (2012), women given information on and instruction about BSE and breast cancer by healthcare professionals demonstrated higher knowledge and confidence and tend to practice BSE more than those who receive information from other sources.
Moreover, practicing monthly breast self examination beginning at age 20 can play an important role in early detection of breast cancer resulting in greater chances of cure and less complex treatment (Berman, Kozier & Erb, 2008). According to Atanga, Atashili, Fuh, and Eta, (2012) regular practice of BSE is the corner stone of the fight against breast cancer worldwide, especially for black women because clinical breast examination and mammography might not be accessible to them for economic or other reasons. Though screening mammography is widely practiced in developed countries, it is hardly recommended for those under 30 years because of their dense tissue which makes interpretation of the films difficult (National Breast Cancer Foundation, 2012). Furthermore, BSE is still recommended as a general approach to increasing breast health awareness and thus potentially allow for early detection of any anomalies (Ginsberg, Lauer, Zella, Bacten & Baltussen, 2012). Therefore, BSE becomes particularly important and appropriate.
Based on the fact that a greater percentage of Nigerian women die because of late detection and that awareness on BSE increases the possibility of early presentation and consequently reduces mortality, this study is designed to determine the breast cancer awareness and practice of BSE among women in selected rural communities who constitute the majority of women at risk both for the disease and late presentation.
Statement of problem
Prognosis and survival rates for breast cancer vary greatly depending on the cancer type, stage, treatment and geographical location of the patient (Fasoranti, 2010). Survival rates of breast cancer in the western world are high as eight out of ten women in England diagnosed with breast cancer survive for at least five years. In developing countries, survival rates of breast cancer are much poorer. Lack of awareness of early detection measures and screening for breast cancer is common in developing countries (Hanna & Kangolie, (2010)
Salaudeen, et al (2009) asserted that the black woman usually presents late for treatment of breast cancer with a bigger mass and seems afflicted with a biologically more aggressive tumour. Jebbin and Adotey (2009) reported that many cases of carcinoma of the breast they found in the clinic were advanced, with large tumours and multiple nodal involvements and have poorer clinical and pathological prognostic outcome. Jebbin and Adotey, 2009, believe that if women in Port-Harcourt are knowledgeable about BSE and practice it, this scenario may not be so. Similarly, at the surgical unit of Imo State Teaching Hospital, women with breast cancer are presenting with advanced stages of the disease. As a result of late detection of breast cancer, five women of Umuowa died of breast cancer between March and June, 2010.
Otunne (2008) acknowledged that following hospital records in Nigeria breast cancer is truly an epidemic among women, as it was estimated that 211,000 new cases of invasive breast cancer was diagnosed in 2007 and 43, 3000 patients died of this disease in Nigeria. Tara, et al (2008) noted that the earlier a woman is diagnosed of breast cancer, the better her chances of survival. Since there is increased mortality in Nigeria due to late detection and late presentation, one begins to wonder if women are aware of breast cancer and if they practice BSE. This study is therefore set to empirically ascertain the breast cancer awareness and practice of BSE among women in Umuowa community.

Significance of the Study
The findings of this study will help to provide information on breast cancer awareness and practice of BSE among women in rural communities of Umuowa of Imo State. If the information obtained indicate that the women have poor awareness of breast cancer and do not practice BSE or do not do so adequately, it will sensitize health workers to the needs of the women and health-educate them accordingly. This will help in the delivering of focused and directed health talks to the women in the rural areas on the meaning of BSE, meaning of breast cancer and the proper steps used in BSE. This will in turn increase attention to and practice of BSE among rural women.
When the findings of this study come to the awareness of other Government Health Agencies, it will assist them in devicing the means
