Effectiveness of educational intervention on breast self-examination amongadolescent girls to prevent breast cancer: a comprehensive review

Abstract

Breast cancer remains the most frequently diagnosed malignancy among women worldwide and represents a major public health burden, particularly in developing countries where late-stage presentation is highly prevalent. In India, increasing incidence rates, limited screening infrastructure, socio-cultural stigma, and poor awareness regarding preventive practices contribute significantly to delayed diagnosis and high mortality. Breast Self-Examination (BSE) is a simple, low-cost, non-invasive, and easily accessible method that promotes breast awareness and facilitates early identification of abnormal breast changes. Among adolescent girls, early introduction of BSE education is especially important because adolescence is a formative stage during which lifelong health behaviours and attitudes are established. However, despite the importance of preventive awareness, baseline knowledge and practical competency regarding BSE among adolescents remain considerably inadequate due to educational deficits, cultural taboos, fear, embarrassment, and misinformation. This comprehensive review evaluates the effectiveness of educational interventions on improving knowledge, attitudes, and practices related to Breast Self-Examination among adolescent girls for the prevention and early detection of breast cancer. The review synthesizes evidence from school-based programs, nurse-led interventions, peer education models, digital learning systems, audio-visual teaching strategies, and community awareness campaigns. Literature findings consistently demonstrate that structured educational interventions significantly improve post-intervention knowledge scores, practical competency, confidence, and willingness to perform regular self-examinations. Interactive teaching approaches, particularly demonstrationreturn-demonstration methods using anatomical breast models, audio-visual aids, peer-led discussions, and digital reminder systems, were found to be highly effective in reducing anxiety and enhancing skill retention among adolescents. The review further identifies multiple barriers influencing BSE practices, including cognitive deficits, sociocultural modesty, psychological fear of diagnosis, family silence, institutional gaps in school health curricula, and limited availability of trained educators. Nurse-led educational initiatives emerged as one of the most successful approaches due to the ability of healthcare professionals to provide culturally sensitive counselling, individualized guidance, and structured competency-based training. Community-based mother-daughter workshops and multilingual educational materials also play an essential role in reducing stigma and improving acceptance of breast health discussions within families and communities. The findings emphasize the urgent need for integrating mandatory breast health education into national school curricula and strengthening school health services through trained nursing personnel, practical demonstration facilities, and accessible educational resources. Public health systems should also utilize digital platforms and community outreach programs to ensure continuous awareness among both school-going and out-of-school adolescents. Establishing coordinated referral pathways between schools, community clinics, and diagnostic centres is equally important for ensuring prompt clinical evaluation of detected abnormalities. In conclusion, educational interventions are highly effective in enhancing Breast Self-Examination awareness and practice among adolescent girls and can substantially contribute to early detection of breast cancer. Longterm institutional implementation of structured, culturally appropriate, and multi-modal educational programs has the potential to reduce delayed diagnosis, improve survival outcomes, empower young women with preventive self-care skills, and strengthen community-level breast health awareness.
